I've been curious about using a peated whisky in a sauce, but I'm not sure I want to use something so expensive on something that may be unpleasant tasting, or at least crowd out other flavours.
I mostly cook with white wine or beer when I make roasted chicken. Just cut the chicken, put salt and pepper in there, some olive oil and salt on the oven's plate and put in there for about half a hour. When is half cooked I will mix water, beer or wine and half chicken cube. It leaves a great sauce to eat with your chicken alongside smashed potatoes.
