The first time I bought a half hog directly from the farmer, I asked for the lard. They were surprised I wanted it and the butcher gave me a whole 2 gallon
bucket of it, no additional cost. That gravy train didn't last long, because the people selling the hogs found out their customers (they had a CSA) wanted good lard so pretty soon the butcher was selling it and the hog farmers were selling it and it got in short supply.
When I moved here, I found a neat meat store where the guy either raises his own animals or buys them from a few select farmers. They also didn't realize the value of lard and sold me pork fat for $0.20/lb to make my own lard. It's not hard - you remove all the fat and cut it into strips or small chunks then slow-cook it - crock pot,
oven, or stovetop all work. Just don't let it brown or burn or it will get a meaty smell that's not great in
apple pie crusts, LOL!
So instead of looking for just lard, why not look for people who
sell pastured pigs, like through localharvest.org or even craigslist or farmer's markets and see if you can get either lard or fat from them?
