Heat
Chili, pepper, mustard and ginger write a temperature the table either expects or refuses.
Flavour is the shared problem every cuisine solves differently — heat, ferment, fat, acid and aroma in a ratio a diner can name.
Ferment
Kimchi, miso, garum, cheese and sourdough add time as an ingredient.
Fat
Butter, lard, coconut, olive oil and schmaltz carry aroma and calm spice.
Acid
Vinegar, citrus, tamarind and yogurt cut richness so a meal can continue.
Aroma
Smoke, herb, spice bloom and toasted grain are what memory actually stores.
