ARRACACHA
Costa Rican Vegetables ARRACACHA Taxonomy a. Family- Apiaceae, Arracacia xanthorrhiza. b. Andean native. Description a. PLANT: The green to bronze colored leaves are divided into 3-7 leaflets with serrated margins. They emerge from long petioles similar to celery in a rosette fashion from a cylindrical stem approximately 10 cm high with a 10 cm diameter. b. FLOWERS: Umbels with small purple flowers. c. EDIBLE PORTION: The tuber is a fleshy, underground storage organ being 5-25 cm in length and 8 cm in diameter. Colors range from white to yellow. It is harvested botanically premature, about 4 months after planting. Food value, commercial usage a. Vegetable- It can be eaten raw, but when cooked, its flavor has been described as “a delicate blend of celery, cabbage, and roasted chestnuts.” This root is basically used in any way a potato is used: dumplings, gnocchi, coarse flour, fried chips, biscuits, etc. It is a good food source for babies because it is highly digestible. Young stems can be eaten as greens, and the leaves are commonly used for livestock feed. b. Nutrition- It is rich in carbohydrates, calcium, other vitamins and minerals, and in the yellow cultivars, beta-carotene. Costa Rican Vegetables Breadfruit I. Taxonomy Family Moraceae Artocarpus altilis The breadfruit is indigenous to the South Pacific and Southeast Asia. II. Description Plant: Tall tree of 12m or larger. Sensitive to cold and thrive only in tropical lowlands. Leaves: Large, distinctive, deeply lobed leaves. Fruit: A large, multiple fruit which is formed from an entire flower cluster is usually rounded in shape. It has a green, relatively smooth skin that becomes yellowish as it ripens. There are two types: The breadfruit the ordinary seedless type and the breadnut which has large edible seeds. III. Food value, usage Both breadfruit and breadnut have to be cooked. They have no distinct flavor and are mainly a starch source. They are used to “stretch” a curry or stew and absorb the flavor of the met and other foods. Breadfruit contains 25% carbohydrates; it also supplies small amounts of minerals and vitamins. Costa Rican Vegetables CARROT Taxonomy a. Family- Apiaceae, Daucus carota b. Native to Afghanistan. c. If garden carrots’ seed is collected and sown the next season, the plant is reverted to its native form, similar to what is known as Queen Anne’s Lace. d. The 4 common cultivars in western markets include: Imperator (the most commonly seen), Nantes, Danvers (often used for baby food puree), and Chantenay (typically diced for canned and prepared foods). Description a. PLANT: A rosette of leaves grows from seed, or the taproot. b. FLOWERS: A biennial, it flowers the second year with an umbel inflorescence, after spending the previous year storing energy in its large taproot. Is used for seed collection, flowers are typically bee pollinated, creating another source of revenue for farmers. c. EDIBLE PORTION: The woody textured taproot, varying in colors from orange to white. Food value, commercial usage a. Vegetable- The taproot can be eaten raw or cooked in a variety of culinary ways. It is highly processed, being jarred, canned, frozen, and as an ingredient in prepared foods or meals. b. They have been breed to contain a wide variety of pigments that produce colors of orange, yellow, white, maroon, and purple. c. Nutritionally, the carrot is famed for its beta-carotene, which causes the orange coloration, and is a prerequisite for Vitamin A. Carrots are also high in fiber, antioxidants, and minerals. Carrots, bred for a white color, are high in tocopherol (Vitamin E). Costa Rican Vegetables Cassava I. Taxonomy • Euphorbiaceae family, with rubber and poinsettias. Manihot esculenta. Native to Brazil and Paraguay, now grown pantropically. • II. Description Plant: The cassava plant is a tall (6-8 ft), semi-woody perennial, with fairly large, palmately compound leaves. Tuber: The edible, tuberous roots reach anywhere from 8-30 inches in length and are 1-3 inches wide. They contain white or yellowish flesh surrounded by a thick, brown, detachable rind. Flowers: Separate male and female flowers, both very different in appearance. The staminate flowers are white to red with darker red insides, while the pistillate flowers are green. Fruit: The cassava fruit is round, oblong, and winged. The color changes from a green to a dark brown as the fruit matures. Each fruit contains 3 seeds. Food value, usage • Cassava contains 25 – 30% starch and is one of the major sources of calories in the tropics. It is also high in vitamin C. Tubers are low in protein; must supplement w/ other foods to maintain a balanced diet. • Tubers come in two varieties—bitter and sweet. The bitter contains cyanide and must be processed before consumption. Can be used in commercial production of cyanide. • Cassava tubers are ground into flour that can replace wheat flour. • The juice can be developed into cauim, a mild alcoholic beverage popular in parts of the tropics. The concentrated juice is flavored into a substance called cassareep, used to flavor meats and other foods. • Cassava is the source of tapioca, made by grinding the tubers in water and boiling away the excess liquid. • The leaves of the plant are also edible, served in a way similar to spinach; high in vitamin A. • The plant is used in substances like starch, soaps, glue, sugar, and acetone. • Cassava leaves and stem meal are fed to livestock. Costa Rican Vegetables CHAYOTE Taxonomy a. Family- Curcurbitaceae, Sechium edule b. Domesticated in Mexico by Aztecs and Mayans. Description a. PLANT: Much like other cucurbits, have large leaves with 3 points, and climbs with tendrils. b. FLOWERS: Small, 5-petaled flower typically of cucurbits. c. FRUIT: Pear-shaped fruit has white flesh around a flattened seed, wrapped in a thin green, wrinkled skin. It has a bland taste, described as a cross between a potato and a cucumber. Food value, commercial usage a. Vegetable- The fruit is horticulturally a vegetable and can be eaten raw, boiled, stuffed, mashed, baked, fried, or pickled. The starchy root can also be eaten by man or as animal fodder. The roots are diced and fried with sweet peppers, sliced and dipped in egg batter before frying, or cooked with meat dishes b. The fruit and seed as high in Vitamin C and amino acids. The leaves and fruit can be used as a diuretic, for cardiovascular health, or anti-inflammatory. The leaves can also be used in a tea for arteriosclerosis, hypertension, and to aid in dissolving kidney stones. Costa Rican Vegetables COMMON BEAN Taxonomy a. Family- Fabaceae, Phaseolus vulgaris b. Origin of America’s. c. Common varieties include: Snap or String, Shell, Pinto or mottled, White, Red, Black, Pink, and Yellow. Description a. PLANT: Bush varieties grow 20-60 cm in height while vining types reach 2-3 m. Alternate green or purple leaflets in 3’s have smooth margins. b. FLOWERS: Small white, pink, or purple flowers produce green, black, yellow , or purple pods, 8-20 cm long. c. FRUIT: The eaten seed is plump and kidney shaped and often mottled with two different colors. They are held within a pod that may or may not be commonly eaten. Food value, commercial usage a. Vegetable- Beans must be boiled at least 10 minutes before eating to destroy the toxic lectin phytohaemmagglutinin which can cause severe gastric irritation. This is not typically a concern, however, since beans must soak in water for 4-10 hours and then be boiled in water for 1-3 hours. Commercial beans are most often precooked and canned, but can also be found fresh, frozen, and in a diverse selection of processed foods and soups. b. Nutrition- Beans are high in dietary fiber and are also a great source of vegetable protein, though not a complete protein alone, is essential to the complete protein of the Three Sisters with corn and squash. Costa Rican Vegetables CRUCIFERS (Broccoli & Cauliflower) Taxonomy a. Family- Brassicaceae, Brassica oleracea b. Mediterranean native. c. In the Simpsons, Treehouse of Horror XI, Homer is killed by eating broccoli, and Dr. Hibbert claims after the autopsy that it is one of the deadliest plants, warning people with its bad taste. Description a. PLANT: This cool weather annual crop, falls apart when the weather warms—but will often be in flower at this point and bitter flavors can quickly develop in the stalk. The principle difference between broccoli and cauliflower is that cauliflower’s flower buds and stalk are blanched by physically tying the leaves over the developing flower heads blocking sunlight, leading to a lack of chlorophyll, toning down the flavor. b. FLOWERS: A crown of edible flower buds would each open into four petals, but is harvested botanically immature. c. EDIBLE PORTION: The flower buds and the pedicle, which is a thick stalk-like structure, are eaten. Food value, commercial usage a. Vegetable- Stalks with buds are popular raw and cooked in a wide assortment of recipes. b. Broccoli and cauliflower are high in soluble fiber, vitamin C, and glucoraphanin, a powerful antioxidant against cancer after it is metabolized to sulfurophane. Costa Rican Vegetables ONION Taxonomy a. Family- Alliaceae, Allium cepa b. Native to the areas surrounding Palestine and into Egypt. It was worshipped by ancient Egyptians from their thought that the onions concentric rings symbolized eternal life. Onions were used in the eye sockets of King Ramesses IV with the thought that the strong scent of onion would bring back breath to the dead. Description a. PLANT: Not of economic importance. Leaves emerge in the spring as tall hollow grass-like structures. Propagation is done often by seed or by bulblets where seed is sown closely together and the small plants produce small bulbs—but this allegedly leads to off flavors and smaller onions. b. FLOWERS: Not of economic importance, except in ornamental varieties. Emerge when foliage begins to die, and bloom as an umbel—appearing like a large seed head on dandelions. c. EDIBLE PORTION: The bulb is a swollen portion of the stem at the plants base where nutrient reserves over winter and then continue growing the next season. Food value, commercial usage a. Vegetable- Bulbs are typically cooked so that the sharp pungency of amino acid sulfoxides which produce the acrid flavor are more mild. Commercially, onions can be purchased fresh, frozen, canned, or dehydrated and are constituents in many processed foods. b. They contain anti-inflammatory, anticholesterol, anticancer, and antioxidant components. They have also shown some effectiveness in fighting colds, heart disease, diabetes, and osteoporosis. Costa Rican Vegetables Peach Palm or Pejibaye I. Taxonomy • • • • Bactris gasipaes (pejivalle, piva) Arecaceae fam ily Indigenous to Am azonia, spread into central Am erica by Indians. Grown throughout Central and South Am erica in hot, wet lowlands to 1000 m . Propagated from seed or suckers; spineless selections are available to perm it easy clim bing. II. Description. • • • Plant: Erect, rapid growing palm to 15 m , often with m ultiple trunks .8 inches thick. The trunk has long, sharp, black, num erous spines. Flowers: Monoecious or herm aphroditic, flowers borne in spadices 8-12 inches long. Fruit: Borne in clusters of 50-100, weighing 25 lbs or m ore. Bearing begins in 6-8 years from seed. Fruit color varies from yellow-scarlet when im m ature to purple at m aturity; Ovoid or conical, 1-2 inches long, persistent cup-shaped calyx at base (3-lobed). Flesh is yellowish, sweet, occasionally bitter, dry, and m ealy. A single conical seed (3/4 inch) is found in the center; som e types parthenocarpic. III. Food value, usage • • • Fruits are high in fat and fiber, low in water, com pared to other fresh fruit. Fruits are often fed to poultry and livestock. Another food product, “heart o’ palm ” is derived from the large apical m eristem of the palm , on plantations of low-growing trees (2-3 m ). Costa Rica is a m ajor producer of heart ‘ palm . Costa Rican Vegetables PEPPER Taxonomy a. Family- Solanaceae, Capsicum annuum b. Cultivated originally throughout South-Central America. c. Other species of importance include C. baccatum, C. chinense, C. frutescens, and C. pubescens. Description a. PLANT: Alternate, elliptic, simple, smooth edged leaves, ~2-4 feet tall. b. FLOWERS: White to greenish white, typically on a pedicel, solitary or in groups of 2-3, with 5 lobes and wheel shaped. c. FRUIT: Pod shaped hollow berry, with an empty cavity, ranging in colors from green to red to black. All are edible with varying degrees Food value, commercial usage a. Vegetable- Fruit is used in a wide array of raw and cooked manors for food. May be preserved by canning or drying. b. Spices- Fruit may be ground and dried or used to take extracts to create sauces which are kept edible with various synthetic and natural preservatives. c. Medicine- Modern societies use the chemical Capsaicin, which causes the spicy sensation and found in highest concentrations in the placental tissue, principally in topical applications as a pain reliever and circulatory stimulant. Capsaicin has also been used as a laxative and been linked to preventing prostate cancer. Traditional uses include these as well as against ailments caused by microbes—showing capsicum’s potential for anti-microbial activity. Costa Rican Vegetables Potatoes I. • • • Taxonomy Family Solanaceae, Solanum tuberosum. The world’s most important non-cereal crop. Originally from the Andes (Peru); now grown worldwide II. Description Plant: Sprawling, herbaceous plant similar to tomato, reaching 1 m. Pinnately compound leaves 10” long, leaflets 3”. Leaves and stems are poisonous. Tubers: Tubers (modified underground stems used for storage) vary in shape, size and color, and store starch primarily. The tubers are the only edible part of the plant. Flowers: Flowers can be white, pink, lavender, or light blue, with yellow centers, about 1” diam, star-shaped, borne in small axillary clusters. Fruit: Small, spherical, 1” fruit resemble a small green tomato. Contains several hundred small seeds. Fruit is poisonous. Food value, usage • • • Potatoes are high in carbohydrates, mostly starch, with 278 calories in an ordinary potato. They contain small amounts of protein, minerals (e.g. K), and vitamin C. Potatoes feed both people and animals, being commonly used as fodder for herds and livestock. Potato plants have high concentrations of solanine, a poisonous chemical. Though the tubers are edible, even they can become poisonous if allowed to rot or if eaten in massive quantities. Cultivated potatoes are bred to have low solanine levels. Costa Rican Vegetables SQUASHES Taxonomy a. Family- Curcurbitaceae, Curcurbita maxima (large winter squash, buttercup, have a spongy peduncle. . .), C. pepo (yellow squash, zucchini, pumpkin, acorn squash, spaghetti squash . . .), C. moschata (butternut . . .), C. mixta (cushaw varieties). b. North American native. c. Squash can be broadly categorized as winter or summer, depending on the season they are harvested. Description a. PLANT: Non-climbing vine, sprawls over the ground. From this habit it works as a ground cover to repress weeds and was apart of native’s three sisters along with corn and beans. b. FLOWERS: Five, fused yellow petals create a tube like flower that must be pollinated, or the newly developing fruit will often be aborted. Honeybees are the popular choice since they produce a second harvestable product. Traditional the squash bee pollinated the flower, but their populations have declined, presumably from heavy pesticide use. c. FRUIT: A pepo, or hard-rind berry. Summer squash is harvested premature, winter squash at the end of the summer when it is more mature and left in a cool place to harden off the skin. Food value, commercial usage a. Vegetable- Fruit can be eaten raw, more common with the summer squash, or in a wide variety of cooked recipes. Seeds can also be eaten raw, cooked, crushed into a paste, or used to extract oil. Shoots, leaves, and tendrils are also edible. Flowers are often used in many culinary dishes, often stuffed and fried. b. Two common pests are squash vine borer and squash bug. Costa Rican Vegetables Taro (Tiquisque & Ñampi) Taxonomy • Family Araceae, Closely related to elephant ear, caladium. • Cultivated for over 6,000 years in the swampy regions of southeastern Asia • A traditional staple in many tropical regions, particularly Hawaii, Pacific islands. • • • • • Asian version (Colocasia esculenta) • Dasheen, poi, tiquisque American version • yautia - malanga - chamol ñampi (Xanthosoma spp) Toxic if not properly prepared Many ornamentals in this family Elephant's ear (Alocasia), caladium, anthurium, etc. Description Plant: A terrestrial aroid, with large, arrowhead-shaped leaves growing in clusters, up to 3 ft. Stems are short, thick and purple. Like all aroids, leaves emerge from the petiole sheath of the previous leaf. Corm: Taro has a short underground stem called a corm, which is starchy, thick, reaching 6” in diameter. It is top-shaped, with rough ridges, small roots, brown skin, and white or pinky inner flesh. Flowers: A long, erect stalk sprouts from the center of the leaf cluster. A false leaf, called a spathe, grows up to surround and protect and inner cluster of flowers. The cluster has male flowers towards the top and female flowers towards the bottom. Food value, usage • While taro is very valuable as a food plant, it cannot be eaten raw, as the plant cells contain raphides, needlelike forms of calcium oxalate. These irritants can cause gastrointestinal diseases if a person consumes large quantities of unprocessed taro. • The corm of the taro is high in starch and is popular in many tropical dishes, such as poi, a paste-like food from the Pacific islands. The young leaves are eaten like spinach. • Due to its appealing visual nature, taro has common usage as an ornamental plant. • Some of the juices from the leaves and stems are used as dyes. • Taro has a wide variety of medicinal uses. Costa Rican Vegetables TOMATO Taxonomy a. Family- Solanaceae, Solanum lycopersicum b. Cultivated originally throughout South-Central America (Peru-Mexico). c. The word tomato comes from the word tomatl, of the Nahuatl language, a member of Aztecan, from central Mexico. Description a. PLANT: Short lived perennial, cultivated as an annual. 1-3 meters in height, weakly woody stem, similar to a vine in its sprawling habit. Pinnate leaves, 10-25 cm long with 5-9 leaflets, up to 8 cm long with serrated margins. Leaves and stems have dense pubescence of glandular trichomes. b. FLOWERS: Five, yellow pointed lobes create the bloom 1-2 cm across, coming from a cyme in groups of 3-12. c. FRUIT: Produced determinately in many nodes in a single flush (primarily commercial) or indeterminately in the terminal nodes as the plant continues to lengthen. The edible plant portion is a large, bright red colored berry from the pigment lycopene, with a diameter of 1-2 cm in wild species, but up to 10-20 cm in some domesticated varieties. Seeds are held in a gelatinous matrix within each ocular cavity separated by dense fleshy tissue. Food value, commercial usage a. Vegetable- Fruit can be eaten raw or cooked and is used in processing by canning or jarring raw or flavored fruits, or in sauces and juices. Also used largely as a dehydrated and frozen food/sauce in the frozen food industry. b. Medicine- High in vitamin C. The most well known medicinal value is from the pigment Lycopene, a powerful antioxidant, which has been proven to fight against prostate cancer. Costa Rican Vegetables TRUE YAMS (Ñame) Taxonomy a. Family- Dioscoreaceae, Dioscorea sp. b. Independent cultivation origins in Africa, South America, and Asia. c. The slang of ‘Yam’ for sweet potato in the US is a misnomer since sweet potatoes (Ipomoea batatas) are a totally different species. Description a. PLANT: Twining vine with a cordate shaped leaf and prominent veins. b. FLOWERS: Not of commercial importance. c. EDIBLE PORTION: A large tuber, weighing up to 120 lbs and being 7 feet long, it is covered in a tough skin that softens when heated for easy peeling. Certain species, particularly African ones, are poisonous if consumed raw, but all, excluding certain Asian varieties, are cooked to remove bitter alkaloids. Colors range from the typical white or pale yellow to orange. Food value, commercial usage a. Vegetable- A staple food crop to many native cultures, it is thought of as a potato substitute, though in these areas the potato was introduced long after cultivation of yams. It is cut julienne and briefly soaked in vinegar and eaten raw in some Asian meals. More commonly, it is chopped and grilled, baked, or fried, or ground into a paste and cooked to create a rice-like consistency. b. Medicinal- The alkaloid diosgenin is the most significant in terms of commercial value. It is a precursor for different hormonal drugs and makes up roughly 50% of the raw material for cortisone, progesterone, and contraceptives.
