I don't think it really matters which part you use, RD.
However, I've long ago stopped using cloves (apart from in making Garam Masala). I don't think they are a "typical BIR" ingredient.
I think they are largely a Pat Chapman (and a traditional Indian cooking) ingredient.....and that is not meant to be a criticism of Pat Chapman (I have great admiration for his contributions to BIR cooking).
