My mother's shortbread cookie recipe has always been THE recipe to use but whenever I made it mine were, in the opinion of my father, either too "short" or not "short enough". I tried everything, even other recipes to no avail. So this year I got out my wonderful Kitchenaid Pro, attached the dough hook, added all the ingredients of mother's recipe and turned on the machine! I know, shortbread and machines should never mix but it was THE best shortbread I have ever made. Funniest thing - my Dad said, "hmm I am glad your mother isn't here because she'd kick me for saying this....it is way better than hers!"
