I don't know if that's 12 pieces of chicken, or 1.5 pounds, or 2 pounds, or????
So I won't make it with chicken, but might try the sauce and see how much I get. All this "use two pans" stuff? The recipe is, in other words, poorly written and needs an editor. It might be a really good recipe, but seeing the way it's written doesn't instill trust.
12 Pounds?? Hope that's supposed to say 2
