What is jicama?
Jicama, pronounced HEE-kah-mah, is a tuberous root vegetable native to Mexico and Central America. It belongs to the legume family, which includes beans and peas, despite its appearance resembling a potato or turnip. It is crucial to note that only the underground tuber is edible; the rest of the plant, including leaves, stems, and seed pods, are toxic due to a natural insecticide. The root is covered in a thin, brownish skin that must be peeled to reveal the white, crisp, and juicy flesh inside. Its texture is often compared to water chestnuts or firm pears, providing a satisfying crunch popular in salads.
Origin and Background
Historically, jicama has been a significant food source in its native Mexico and Central America for hundreds of years. Spanish traders introduced it to Asia, leading to its cultivation in areas like the Philippines and China. It is also known as Mexican turnip, Mexican potato, or yam bean. Valued for its flavor and hydrating qualities, particularly as a snack, jicama requires a long growing season in warm climates.
Flavor and Texture Profile
Jicama offers a unique combination of mild, subtly sweet, and slightly nutty flavor, similar to a less sweet apple or a potato. Its mild taste allows it to absorb the flavors of other ingredients. The flesh is very juicy due to high water content, making it refreshing when eaten raw. Unlike many root vegetables, jicama maintains its crisp texture even when lightly cooked, adding a pleasant contrast to dishes.
Nutritional Benefits
Jicama is a low-calorie, nutrient-dense food. A cup (130g) contains about 49 calories and is rich in fiber and vitamin C.
Rich in Fiber and Prebiotics
A cup of jicama provides over 6 grams of fiber, including prebiotic fiber (inulin) that supports beneficial gut bacteria, aiding digestion and potentially boosting immunity. High fiber also helps with weight management by promoting fullness and regularity.
High in Antioxidants
Jicama is a good source of antioxidants, notably vitamin C, with a cup providing a substantial amount of the daily recommended intake. Antioxidants help protect cells from damage by free radicals, potentially lowering the risk of chronic diseases.
Heart-Healthy Nutrients
The high fiber and potassium content in jicama can support heart health. Fiber helps lower cholesterol, while potassium helps regulate blood pressure.
How to Use Jicama in Food
Jicama is highly versatile and can be used raw or cooked in various ways:
- Raw: It is traditionally eaten peeled and sliced, often with chili powder, salt, and lime juice. It is also a crunchy addition to salads, slaws, and fruit platters.
- Cooked: Jicama keeps its crispness when lightly cooked, making it a good substitute for water chestnuts in stir-fries. It can be boiled and then baked or air-fried as a low-carb alternative to french fries.
- Blended: Its juiciness and subtle sweetness make it suitable for juices and smoothies, particularly with fruits like pineapple.
- Wraps: Thin slices can be used as gluten-free wraps for tacos or sandwiches.
Selecting, Storing, and Preparing Jicama
Selection
Choose jicama that is firm, heavy, and has smooth, dry, unblemished skin. Avoid soft spots, wrinkles, or bruises.
Storage
Store whole, unpeeled jicama in a cool, dark, dry place for up to two to three weeks. Peeled and cut pieces can be stored in an airtight container with a damp paper towel or in a little water in the refrigerator for up to a week.
Preparation
Always peel jicama before eating, as the skin is not edible. Use a sharp peeler or knife. Jicama does not brown when cut, making it ideal for advance preparation.
