Yesterday, I was able to get a pound of grass fed beef fat from Whole Foods, and the butcher was nice enough to give it to me for FREE! I want to make tallow, and I've read Mark's blog post on rendering beef tallow, but I don't have a food processor. Can I just use a crock pot? The fat is cut into large slabs, should I still cut them into little cubes if I'm using just a crock pot? Any suggestions would be great, thanks!
