*Cook's note: Feel free to try any bread, cheese, or jelly in any combination, not just the ones listed here.
Select any bread, any cheese, and any jelly. Spread 2 pieces of bread with butter. Place 1 piece, butter side down, in a skillet over medium heat and top with several slices of the cheese. Spread the unbuttered side of the other piece of bread with some jelly and put it jelly side down on top of the cheese. When the first side is browned, after about 3 minutes, flip the sandwich and cook until the other side has browned, about another 3 minutes. Serve while warm.
