Method 1: thaw the frozen meatballs in the refrigerator, and then fry them at the medium oil temperature of 140℃ until the surface of the meatballs is golden yellow.

Method 2: Put warm oil at about 100℃ in the pot for three minutes, then raise the oil temperature to 140℃ and fry until the surface of the meatballs is golden yellow.

Note: It is best not to soak meatballs in water to thaw them. After the meatballs are soaked in water, they will lose some of their original flavor, and they will absorb water, and there will be serious oil splashing when frying. It's best to thaw it in the microwave oven. When thawing, meatballs should be packed in sealed plastic bags or lunch boxes to avoid losing water and destroying flavor.
