Where does Serrano sit on the ladder?
Rung 7 of twelve — Sting, covering 15K to 35K SHU. Serrano country. The burn now arrives fast rather than building. Keep a dairy source within arm’s reach before your first bite, not after.
What stops the burn from Serrano?
Dairy. Capsaicin is fat-soluble, so water spreads it rather than removing it; the casein in milk, yoghurt or ice cream lifts it off the receptor. A spoonful of sugar held in the mouth measurably helps too. Starch — rice or bread — physically carries it off the tongue.
