The Heritage pig breeds in our country are popping up everywhere. We are going in the opposite direction. Pork fat is good for you. Read Fat the book.
Our ancestors ate lots of pork belly and lardo (cured backfat) and weren’t obese.
RE: Heritage breeds, there’s a farmer near here that raises Red Wattle Hogs. They’re a high fat breed and the chops on them are nearly as marbled as USDA Choice strip steaks. I made one for the wife on my pellet grill and she was blown away. Tender, juicy, with great flavor. Very expensive though so we don’t get them often.
I bought an entire uncured ham from them twice and brined and smoked them myself. DELICIOUS! If you’ve never made your own ham you should try it. It’s easy and you’ll wonder why you’ve never done it before.
