One onion, two slices of ginger, a little soy sauce, a tablespoon of thirteen spices, a teaspoon of salt and pepper to roast pig hearts in the microwave oven. Throw away the pig heart blood clots bought in the supermarket, wash them with blood, cut some (which can be covered) into shreds, and cut them into strips without breaking them. Anyway, it is to remove the fishy smell, coat the pig heart with a layer of soy sauce, sprinkle a little thirteen incense, put the shredded onion and ginger in, draw a few lines outside the pig heart (don't scratch it thoroughly), sprinkle thirteen incense, then find a covered box (use a plate and plastic wrap if there is no box), put it in the cold storage, take it out in 15 minutes, put it in a double-layer plastic wrap bag, and turn the microwave oven to high heat for 5 minutes. Replace it with a double-layer plastic wrap bag, put it in the microwave oven for 5-8 minutes, and take it out. The upper tube will be cooked first, and the plate can be cut off.
