My mum taught my about jam and cheese sandwiches when I was younger. Apricot jam and cheese is my favourite combination, but the cheese has to be fairly thin slices, rather than big hinks of the stuff. It's also nice on toast, when the cheese mlts just a little bit. Everyone I have told bout jam and cheese sandwiches looked at me like I was a fucking nutter.
Also, on the peanut butter (and cooking) front, I made peanut butter pancakes today, and that was the first time I really exerienced the whole sticking to the roof of your mouth feeling and it is really disconcerting! The pancakes were nice enough, and putting butter or maple syrup on them helped, but I needed to ahve a drink to help with the stickiness.
