    A friend of mine was going to deep fry onion rings and when he put the food in the hot oil, it bubbled up and over the sides. It was black. What would cause that? Thanks, Pam

    Boiling over the sides means he had to much oil in the pot or pan. Never fill more than half full.  Black oil is either burnt or full of food particles from previous use.
