Favorites

The recipe for "My Favorite Cookies" is, in fact, my favorite cookie recipe. The recipe began the way many of my favorites do: I found a recipe I already liked, then added a little of this and substituted a little of that. When I do figure out a recipe and it becomes a favorite, I rarely change it. I might make a new recipe inspired by the first, but the first won't change.

Do you have an all-time favorite recipe? What is it?
