"If we're eating an animal, we're eating it from head to toe so nothing is wasted," says our friend Anna Péter—from the Hungarian food blog Malackaraj—in this video that shows how to cook with caul fat, "a layer of fat that surrounds the innards of pigs, cows and sheep." It looks gross when raw but I've tasted it and it's delicious.
Hungarian are like Spaniards, French, and Italians. We eat absolutely every part from anything that moves, flies, or swims, leaving nothing to waste. It wasn't only a matter of survival, but of respect for life: If you are going to sacrifice the life of a being for keeping your own, you should honor that being and treat it with respect, leaving nothing to waste.
