Funny you should mention peanut butter because that is one of the few foods that I don't like along with Cheerios and pickled herring. At the risk of turning this into Boring Thread #2 I'll say that I don't mix sugar and salt like bacon and eggs with pancakes and syrup.
Just a couple of days ago I hid my girl's peanut butter because she left it on the counter.
She was pissed.
