Wow, i would hate to have that kind of reaction to dairy. I have tried a couple different brands of store bought tallow, grass fed, all that, but the best tasting one was the sample i got from the butcher that processed our half cow. Thats why i decided to give it a try, and it wasnt too much work. In youtube i found different methods, but i just picked the one that looked simple. Did mine in the oven, covered, on low heat. Gonna try some today.
