to 1/2 teaspoon crushed red hot pepper

Crushed red hot pepper, commonly known as red pepper flakes or chili flakes, consists of dried and coarsely ground fruits of Capsicum annuum var. acuminatum and related Capsicum species. These peppers are harvested when fully mature and red, then dried and crushed into irregular flakes that retain seeds and placental tissue, which contain the majority of the capsaicinoid compounds responsible for heat. The ingredient originated in Mesoamerica and became distributed globally following the Columbian Exchange, with significant cultivation and processing in Asia, particularly in countries like India, China, and Thailand. Red pepper flakes range in heat intensity from 30,000 to 50,000 Scoville Heat Units (SHU), depending on the pepper variety and growing conditions.

The crushed form features bright red color with visible seeds and membrane fragments, delivering a potent, pungent heat with underlying fruity and slightly smoky notes. The flavor profile includes immediate intense burn followed by delayed heat that builds on the palate, with subtle fruity undertones that vary by regional pepper cultivar.

Crushed red hot pepper serves as a foundational heat element in countless global cuisines. It is essential in Italian cooking, where it flavors pasta dishes, oils, and pizzas, and appears prominently in Asian cuisines—particularly Thai, Chinese, Korean, and Vietnamese—for curries, stir-fries, soups, and condiments. The ingredient is widely used in Mexican, Middle Eastern, and African cooking as well. It functions both as a finishing spice sprinkled over completed dishes and as a cooking ingredient incorporated early to infuse oil or sauce bases. Red pepper flakes pair well with garlic, tomatoes, olive oil, and vinegar, and are commonly combined with salt and oregano in Italian preparations. The flakes are less pungent when cooked into hot oil or fat compared to their raw state.
