YesChilli packs a punch in chilli heat and as such is best used in cautious increments until you find your comfort level.
Or as the good Captain says, until you find your place at the Captain’s table.
If you are making a stir fry for example, start by adding a quarter of a teaspoon of YesChilli sauce or paste to the dish, check the heat levels by tasting the food before cautiously adding a little more as desired.
