First put one-tenth of the weight of the melon seeds in salt at the bottom of the pot to preheat, then when the temperature of the salt reaches 40 or 50 degrees, pour the melon seeds in, and use low heat to fry evenly. Stir-fry for about fifteen minutes. You can feel the melon seeds a little hot with the back of your hand. This way, the color of the fried melon seeds will not change, and the melon seeds will taste a little hard and crisp.
