capsicum

Capsicum is a genus of flowering plants in the nightshade family (Solanaceae), native to Central and South America and now cultivated worldwide. The fruit—a hollow berry containing numerous flat seeds—is commonly referred to as a pepper, though it is botanically unrelated to black pepper (Piper nigrum). Capsicums vary widely in size, shape, and color, ranging from small, elongated chilis to large, blocky bell peppers. The flavor spectrum extends from sweet and mild to intensely pungent, depending on variety and the presence of alkaloid capsaicinoids, which produce the characteristic heat sensation.

Commercial varieties are broadly categorized by heat level: sweet bell peppers (zero capsaicinoid content), moderately hot types (Anaheim, poblano), and extremely hot varieties (habanero, Carolina Reaper). The flesh may be green, red, yellow, orange, or brown depending on ripeness and cultivar. Immature capsicums are typically firm and grassy; fully ripe specimens are sweeter with thin-walled flesh ideal for fresh consumption.

Capsicum functions as both a vegetable and a flavoring agent across global cuisines. Fresh capsicums are eaten raw in salads, sliced as crudités, or roasted to develop sweetness and smokiness. In cooked applications, they serve as a foundational aromatic (like the soffritto of Mediterranean cooking), stuffed whole, grilled, or incorporated into sauces and stews. Dried capsicums are ground into paprika or chili powder, essential to Hungarian, Spanish, and Mexican cuisines. In Asian cooking, fresh and dried capsicums appear in curries, stir-fries, and fermented preparations. Heat-tolerant varieties provide the pungency prized in hot sauces, condiments, and spice blends across Africa, Asia, and the Americas.
