chilli pepper

Chilli pepper (Capsicum annuum and related species) is a fruiting plant native to Mesoamerica, now cultivated worldwide. The peppers are characterized by their pungent, heat-inducing compounds—primarily capsaicinoids—which vary widely by variety and maturity. Fresh chilli peppers range in color from green (unripe) to red, yellow, orange, or brown (ripe), with pod shapes including long and slender, short and squat, or curved forms. Popular varieties include jalapeño, habanero, Thai bird's eye, Scotch bonnet, and cayenne, each with distinct heat levels (measured in Scoville Heat Units) and flavor profiles ranging from fruity and floral to earthy and smoky.

The heat intensity and flavor profile depend on variety, growing conditions, and maturity stage, with ripe peppers generally containing more capsaicinoids than green ones.

Chilli peppers are foundational ingredients in cuisines worldwide, particularly in Mexican, Indian, Thai, Korean, and West African cooking. Fresh peppers are used raw in salsas, ceviche, and salads; roasted or grilled as standalone sides; or incorporated into sauces, curries, and stir-fries. Dried chillies provide concentrated heat and complex flavors in mole sauces, chilli powders, and spice blends. Fermented chilli pastes (such as gochugaru and sambal oelek) are staple condiments across Asian cuisines. The intensity of heat can be modulated by removing seeds and membranes (where capsaicinoids concentrate) or by balancing with cooling elements like lime, yogurt, or coconut milk.
