炸甜甜圈彻底直到它'外面的金棕色，然后切成两半。如果它'煮熟而不是在中间煮熟，你对煎炸甜甜圈的温度很高。如果它's raw in the middle, lower the temperature of the burner and wait a few minutes for the oil to cool slightly before trying again. if it takes longer than 2–3 minutes per side to fry the donuts, raise the temperature of the burner and wait a few minutes for the oil to warm up.
