The temperature of the oil is controlled at about 180-200 degrees. Whether the fritters can be fried and loose, and crispy, and yellow, and fragrant, the production of the main points are: each two up and down stacked, with bamboo chopsticks in the middle of the pressure; can not be pressed too tightly, so as to avoid the two sticking together, the two blocks of the edge of the dough absolutely can not be adhesion; can not be pressed too light to ensure that the fritters in the frying two not separate;
