Pan-Roasted Chicken Breasts with Asian Butter Sauce

This marinade calls for kaffir lime leaves, a marvelously aromatic ingredient that can be found fresh or frozen at Southeast Asian grocers. If you live in an area where citrus grows, you can also grow your own in pots or in the ground. Substitute lime zest if you can’t find them. This recipe makes a generous amount of sauce; use as much as you like.
