Flavor profile

Piquancy is not a taste — it activates pain receptors (TRPV1 and other transient receptor potential channels) rather than taste receptor cells on the tongue. Capsaicin (from chili peppers) activates TRPV1 most strongly, producing the burning sensation primarily in the mouth and throat; fat-soluble capsaicin lingers. Piperine (black pepper) also activates TRPV1 but more briefly and primarily in the front of the mouth. Allyl isothiocyanate (mustard, horseradish, wasabi) activates TRPA1 (a different receptor) and is water-soluble and volatile — the heat is immediate, sinus-clearing, and dissipates quickly. Gingerols (fresh ginger) and shogaols (dried ginger, more intense) activate both TRPV1 and TRPA1, creating complex, warming heat. The culinary application of piquancy: heat builds appetite and flavor perception by increasing circulation and saliva production; it contrasts sweet and fat ingredients (the chili-chocolate, the pepper-cream pairings); it provides a finishing sensation that signals a dish is complete. Training heat tolerance is real — regular capsaicin exposure downregulates TRPV1 sensitivity.
