I tried to render some fat tonight from Kroger beef.
I've done this before and tallow is usually hard and white. You can snap it. What I got from this Kroger beef was not hard at all. It was exactly what the fat looks like in documentaries about liposuction. It was not cow fat. What the fuck is it?
...and after reading this I'm not keen on trying it again:
"Most of the serious toxins that you read about are lipophilic (or, hydrophobic) and hence will tend to partition into animals’ fat in the wild (i.e. bioaccumulate). Examples include dioxins, PDBEs, PCBs, etc."
