red chili pepper flakes

Red chili pepper flakes are crushed or ground dried red chili peppers, typically produced from varieties such as Cayenne, Árbol, or other hot pepper cultivars. These flakes retain both the seeds and pod material, resulting in a coarsely textured spice with visible red fragments and occasional charred specks. The flavor profile is intensely hot with fruity, slightly smoky undertones, and the heat level—measured in Scoville Heat Units—varies by source pepper variety, generally ranging from 30,000 to 50,000 SHU for common commercial versions.

The production process involves drying fresh red peppers (often in the sun or using mechanical dryers), then coarsely grinding or crushing them to create flakes. This minimal processing preserves the volatile capsaicinoid compounds responsible for pungency and the essential oils that carry the pepper's complex flavor notes.

Red chili pepper flakes are widely used across Mediterranean, Asian, Latin American, and Indian cuisines as a foundational heat source and flavor component. They are essential in Italian cooking, appearing in dishes like pasta arrabbiata and in the classic seasoning condiment peperoncini. Asian cuisines employ them in stir-fries, curries, and as table condiments; they are central to Korean and Thai cooking. The flakes are also used in pizzerias, on grilled meats, in soups, stews, and grain dishes, or simply sprinkled as a finishing heat element. Their dry form allows for even distribution throughout dishes, and they can be bloomed in hot oil to intensify and distribute their flavors before adding other ingredients.
