I love to cook and I love spicy peppers. Recently, I've been combining the two.
Ancho peppers are sun-dried and as healthy as nature made them. They have mild to medium heat with a sweet fruity flavor; the flavor reminds you of cherries and prunes. The peppers are used often in Mexican cooking, such as mole (which is a dark sauce containing peppers and chocolate -- yes, chocolate!).
Not all peppers are spicy. Anchos, for example, are quite mild. I add them for flavor, not heat.
Two other popular peppers you should know are spicy. They are jalapenos and habaneros. Jalapenos, despite their reputation, are only medium-heat. I eat them raw and whole. They have a nice vegetably flavor which matches their green color. You can toss a few in any dish to improve its flavor. They add a modicum of heat.
Do you ever cook with peppers? Or hot sauce?
