cassava
Cassava roots are predominantly carbohydrates and provide resistant starch; they are low in protein and fat but rich in vitamin C and minerals such as potassium and manganese. Cassava leaves are protein-rich and highly nutritious when prepared.
About
Cassava (Manihot esculenta) is a woody shrub native to South America, cultivated throughout tropical regions for its tuberous, starchy roots. The plant produces elongated, tapered roots measuring 15–30 cm in length, with rough, brown skin and pale, cream-colored flesh. The roots are mild-flavored with a neutral, slightly sweet taste and contain high levels of resistant starch. Two main varieties exist: sweet cassava, which is non-toxic and edible when boiled, and bitter cassava, which requires processing to remove toxic cyanogenic compounds (linamarin). Bitter cassava is traditionally processed into cassava flour, gari, and cassava starch through fermentation and extraction methods.
Cassava is a critical staple crop in tropical developing regions, particularly in West Africa, where it serves as a primary carbohydrate source. The plant is exceptionally drought-tolerant and grows in poor soils, making it resilient to climate stress and food insecurity.
Culinary Uses
Cassava is prepared across multiple culinary traditions. Boiled or fried cassava roots are served as a side dish throughout tropical Africa, Latin America, and Southeast Asia. Cassava starch is refined into tapioca pearls, used in beverages and desserts, or processed into cassava flour for baking and thickening applications. In West Africa, cassava leaves are cooked as a nutritious leafy green accompanying stews. Gari, a fermented cassava granule, is used to make pap—a porridge staple in Nigeria and Ghana. Cassava is also processed into bread (cassava bread), chips, and gluten-free flour products for modern baking.
