Mask (food)
In the case of slaughter, a mask is understood to be the halves of the face that are used to make pork head jelly in the slaughter process or in the food industry.
After the actual slaughter of a domestic pig , the head of the animal is divided into two halves and, after rough cleaning, boiled at 100 ° C and preserved with nitrite curing salt and given a fresh color, i.e. red. Then the so-called masks are removed from the skull by hand and sent for industrial grinding.
