Non-sous vide cooking times are determined by when the center of the cooked item reaches a few degrees below the targeted temperature. Then heating should be stopped immediately. While the food rests, residual heat will continue to cook it for a while. If the heating continues, the food will be overcooked. Sous vide cooking continues until the center of the food has reached its target temperature. If it continues after this, the food will not be overcooked, and it will not cook more after it stops being heated. The time taken for the center of food to reach the target temperature depends on the initial temperature, the thickness and shape of the food, and the temperature of the bath.
