This recipe, Pikantiko Kotopoulo me Piperes, is adapted from "The Glorious Foods of Greece." I make it with chicken breasts, skinless but on the bone. You can use a cut up chicken, thighs, or what ever you like and you can adjust the heat and the garlic to your taste. The butter (in Epirus it would be sheep's milk butter) and the spices give this a wonderful flavor and wait till you smell your kitchen when it's cooking. If you must, you can substitute olive oil for some or all of the butter, but a whole layer of flavor will be lost.
