Bear fat in particular must be rendered immediately upon killing and slaughter because it is highly susceptible to spoilage in its raw form. After rendering, bear fat can be used in cooking, soap- and candle-making, as a mechanical lubricant and even as a protective finish for leather and wood.
plz note that the best thing to do with bear grease is to wrap a towel around the tip of an arrow soak it in fat and then shoot over a cliff or long drop and watch the fat splatter all over and catch on fire such a beautiful sight to c at night .p.s im not crazy
