Tricks I learned from my mother

Recently I started doing something my mother always did...whenever she would cook bacon, she would keep the grease as she called it (fat) into a little jar.  When she cooked green beans, she would plop a little grease in there to give a little bacon flavoring.
Now cause of the obvious health concerns, I will not do this too often, But come on....Who hasn't been eating some green beans and said...Man I would love some bacon right now!!!!
Problem solved!!!

What tips/tricks have you learned from your mother?
