Cut off and use only the fat from the flank and rump. The more fat and less meat the better. Slowly fry the fat, just like bacon, to remove the fat from grisle and meat etc. Use a pot twice as big as the amount of fat you are cooking. I had 3#lb of fat and used a 16 qt. Expect to cook for 4 hours. I did mine outside on the barbacue so I wouldn't be divorced and I used an old pot from a re sale shop. Careful not to burn the fat by adding a couple of talbespoons of oil to begin with. Stir as needed and if you use charcoal rotate the kettle. After a hour or two you have nothing left but the material that won't melt, like meat etc. Those are called "cracklins". Scoup and drain those out and maybe add more fat and put the cracklins out for birds and squirrels. When you are done allow to cool. When cold the grease will solidify. Now add equal amounts of water to your grease(by guessing) and boil the mixture all over again. This will take 2 hours. When you have a good rolling boil for a half hour or more allow to cool again. Some people will pour this through cheese cloth. I allow mine to solidify again and I scraped off all but the very bottom. The water goes down to the bottom of the pan, the tallow goes up. The pureer stuff is on top. As you get closer to the water line the smell and inpurities increase. You will see the tallow turn from mash potatoe white to bacon grease yellow. I then packed mine in canning jars with any old lid that fit and put them in the freezer. I kepted 1/2 cup out and added 4 tablespoons of olive oil to it after I nuked(microwaved) it for 1 1/2 minutes. It is almost ordorless. Stir it in and allow to solidify again. If you don't, it will be rock hard. Now use it for whatever you want. The half cup is in a tupperware container with a snap on top on my work bench now for over a month. Air tight and dark and it should last for a very long time. Tallow is good shoe polish, hand lotion, patch lube, rust preventative on metal,, laxative and ????
I have noticed as a patch lube it seals much better than any commercial lube therefore, I think it needs less of a charge for a similar trajectory. :thumbsup:
