In a small skillet sautÈ the shallots in 2 tablespoons of the butter until softened and translucent. Do not allow to color. Transfer them to a small strainer and allow all juices to drain off. Discard the juices. In the bowl of a food processor combine the shallots with all of the remaining ingredients and pulse to combine well. Check seasoning and transfer the mixture to a large piece of waxed paper. Roll up into a log and wrap in plastic wrap. Store in the refrigerator up to one week or in the freezer up to two months. When ready to use, simply slice off thin rounds of butter and use in place of sauce on top of grilled chicken, fish, meat or vegetables.
