Chili shisha are more of a rarity and something for the hard-boiled. Anyone who has ever used chili to season his meal knows how much it can burn first in the mouth and then in the throat. So also with the shisha. The chilli flavors can be teased out with more and more heat, sometimes less. For example, with Freestyle Grandmaster (orange chilli), the heat is not dominated by the orange, but the more heat is applied, the sharper it gets and the orange takes a back seat.
