I rendered grass fed beef fat in the crock pot this past week - I now have two pints of beautiful tallow. Today, I made ghee for the first time ... it smells & tastes delicious - I could eat the stuff with a spoon!
Yes, I like it too. I did that last summer as an experiment—bought a lb. of grass fed organic butter and the crockpot to render it.
I also like making yogurt in the crock pot.
