[[hot pepper] flakes]]

Hot pepper flakes, commonly known as red pepper flakes or chili flakes, are dried and crushed fruits of various Capsicum species, primarily Capsicum annuum cultivars. These flakes are produced by drying whole hot peppers and then fragmenting them into small, irregularly shaped pieces that retain seeds and placental tissue. The most recognizable variety is the Italian peperoncino, derived from cayenne peppers, which delivers a sharp, pungent heat with subtle fruity undertones. Capsaicin, the alkaloid responsible for the burning sensation, concentrates in the white placental tissue surrounding the seeds, making commercial flakes characteristically speckled with visible white and dark red particles.

Different regional sources—including Thai bird's eye chilis, Mexican arbol chilis, and Indian dried red chilis—produce flakes with varying heat levels (measured in Scoville units, typically ranging from 15,000 to 50,000 SHU) and flavor complexities. Fresher flakes tend to be more aromatic and vibrant in heat, while older flakes gradually lose potency and develop stale, dusty flavor notes.

Hot pepper flakes function as a versatile heat element and flavor enhancer across global cuisines. In Italian cooking, they are essential to dishes such as aglio e olio, arrabbiata, and pizza, where they impart both spiciness and a subtle fruity complexity. Asian cuisines employ them as table condiments, in soups, stir-fries, and fermented preparations. They are frequently used in spice blends, dry rubs for grilled meats, and as finishing garnishes for soups, pasta, and grain bowls.

The flakes dissolve and distribute rapidly in hot liquids but maintain structural integrity in finished dishes where they provide textural contrast. Unlike fresh chilis, they contribute drier heat with less herbaceous character, making them ideal for dishes requiring bold pungency without fresh pepper flavor. Toasting flakes briefly in oil before adding other ingredients amplifies their aromatic compounds.
