Microwave that jar safely

Heloise. Do your readers struggle with the “organic” peanut butter and almond butter? You know the kinds that suggest refrigeration and aren’t pasteurized so they separate and require stirring. Wouldn’t it be nice if you could pop the jars into the microwave for a quick warming to facilitate that process? But that aluminum foil from the “safety” sealer that never comes off and sticks to the rim of the jar will spark and burn when hit by those microwaves, scarry and perhaps dangerous too. I’ve got a simple way to completely remove that foil. Remove the screw-on lid, but before you tug on that seal, you just invert the whole thing onto a warm dry frying pan or griddle. Preheat the pan for 30 seconds or so on your stove, turn off the heat and hold the inverted jar on the hot surface for fifteen seconds or so. Lift it out and the seal will come off cleanly with no remaining metal scraps. Now, any time you want to microwave the whole jar you can do so without the sparks. You’re welcome.
