This is skill number one (starting early cause I have 2 weeks of vacation coming up this month).
I am teaching myself how to make homemade soap.
I know tallow is very good for making a hard long lasting bar of soap. I can't get free beef fat here that I have found, so I found a meat market that sells it fairly cheap.
Tonight I am rendering the first 20 lbs.
I chopped it up in my food processor. Then put it in two large pans of water and boiled it for an hour.
Two by products that I really wan't counting on is cat food:
Or dog food if it makes the cat puke.
And tons of dog food grade broth. The fat smells very fresh and not at all spoiled however I am reluctant to eat it myself not really knowing how clean it is. But it will be canned in a pressure canner and marked for dog food and I will use it to make my home made dog food and treats.
I have strained out the first batch through a colander and then a smaller screen and dumped it back into the pot for more boiliing. When this is cool I will put it in the freezer to solidify the tallow and that will be pulled off and it will be put back into the pot to re-boil. That process will be repeated until the tallow is clean and white.
