Least Favorite Foods?
Black licorice. As a child, my dad would buy Good & Plenty because he liked black licorice and it was the only candy he could keep in the house safely knowing none of us kids would ever touch it.
One day I was telling my aunt about this story and my son was like "what's black licorice?" I was like oh man, you'll have to see for yourself. So I went to the dollar store and bought him a small bag of it and he hated it as much as I do and spit out the first and only bite he's ever tasted of the stuff.
Edited to add Blue Cheese & Raisins. Especially raisins in chocolate chip cookies. I remember when my ex sister in law got married, her wedding cake was laden with raisins. I was like "why would anyone do that to their wedding cake?"
