I have many favorite foods, including many I can no longer eat, but I don't associate them with any particular memories, maybe because I had a pretty happy childhood? Every holiday has favorite foods associated with it in my mind, and some have a particular person - Banana Bread is Uncle Mac's - I've shared his recipe here, butterscotch sauce and hot fudge sauce are Aunt Bertha - even those it's technically her sister Betty's butterscotch sauce recipe, Betty was dead before I was even born, so I associated them with Bertha - but lots of things I love just because!
