I really don't bother with nuts, except when it comes to two, pecans and walnuts. The only reason these give me problems is because my mother doesn't like them. Now I've heard it doesn't matter what you substitute nuts with, but I find that a problem right now because one of my holiday cookies will be a root beer cookie. I don't really know how root beer tastes like or what it tastes good with, but a lot of my friends love root beer which is why I picked them. Could anyone give me a tip on a good pecan substitute for these cookies that isn't walnuts?
