Ground beef already formed into patties or separated into smaller quantities take less time and defrost quicker. For instance, 1/2-inch (1.25-cm) ground beef patties that were frozen separately usually take about 10 hours to defrost.
Gelatin is a protein substance used to thicken liquids. It does not have a color, smell, or taste. It comes from boiling animal tissues such as beef bones, cartilage, tendons, and pig skin. Gelatin is used in many kinds of food products and drug and supplement products.
Is it true gelatin is made from decaying animal hides? How is gelatin made? A friend of mine said he visited a gelatin factory where he saw cow skins piled to the ceiling. The skins are left to putrefy or cure for about a month, during which time they're overrun by rats, mice, and insects. The stench, my friend said, is unforgettable.
