Heat the oil on high and then lower the heat to medium. Slip in the balls into the hot oil from the side of the pan, one by one. They will sink to the bottom of the pan, but do not try to move them. Instead, gently shake the pan to keep the balls from browning on just one side. After about 5 mins, the balls will rise to the surface. The balls should rise slowly to the top if the temperature is just right. Now take a slotted spoon and move it in circular motion in the oil, making sure not to touch the balls. This will shake the balls and even ensure even browing of all the balls.
