pepper flakes

Pepper flakes, commonly known as red pepper flakes or chili flakes, are dried and crushed pods of hot chili peppers, typically Capsicum annuum varieties. The flakes are produced by drying mature red chili peppers and breaking them into small, irregular fragments, which retain the seeds and placental tissue—the hottest parts of the pepper. Pepper flakes range in heat from moderately hot (around 15,000–30,000 Scoville Heat Units) to significantly hotter depending on the chili variety used. The flavor profile includes fruity, slightly smoky notes alongside the characteristic burning heat. The most common commercial pepper flakes are derived from cayenne peppers, though other cultivars such as Thai bird's eye chilies and Spanish peppers are also utilized regionally.

Pepper flakes exhibit a vibrant red to reddish-brown color and coarse texture. The flavor develops complexity when toasted briefly in oil or dry heat, mellowing slightly while intensifying aromatic qualities. Different origins and processing methods yield variations in color intensity and heat level.

Pepper flakes serve as a fundamental seasoning across Mediterranean, Asian, Latin American, and Middle Eastern cuisines. They are most notably used as a finishing spice for pizza, pasta dishes, and soups, where their heat and visible flecks add both flavor and visual appeal. In Asian cooking, pepper flakes feature in stir-fries, curries, and fermented condiments like gochugaru (Korean red chili flakes). They are commonly bloomed in hot oil to infuse its aromatics into a dish or sprinkled raw over finished foods for immediate, pungent heat.

Pepper flakes pair well with garlic, olive oil, vinegar, and tomato-based preparations. They enhance both savory and slightly sweet applications, including chocolate and spiced beverages. Care should be taken during heating, as excessive cooking can produce a bitter taste; controlled, brief heating achieves optimal flavor development.
