If you're called away from the cooker - by the phone, say, or by someone at the door - take pans off the heat. It's the easiest thing in the world to forget about them.
Turn saucepan handles so they don't stick out (and aren't over another ring).
MIX FIRST 4 INGREDIENTS. BRING TO A ROLLING BOIL IN LARGE SAUCE POT. REMOVE FROM HEAT. STIR IN VANILLA AND PEANUT BUTTER UNTIL MELTED. ADD OATS AND STIR WELL. DROP BY TABLESPOON ON WAX PAPER TO COOL.
