There was also always sweet potato casserole [..]

Having had the "pleasure" in the 90s to have my host family mum serve one of those as a special homemade dinner because I mentioned I liked sweet potatoes on a previous visit to the States, I just had a bad flashback... I didn't finish even my first serving and I felt so bad because she had made this for me especially. But... marshmallows! How can people mistake those for something edible???
