Dumb city brought up boy here with a dumb question. What part of the pig is used for bacon. I have cut up deer for meat, and buy a side of cow from a butcher, but never thought about where bacon comes from. Glad you guys got a laugh on me. LOL. Jon
Never know until you ask, Jon, and nobody born knowing it all ! I didn't grow up around butchering on the farm like a lot of folks here, but learned what little I know by simply jumping in.....oh, and I AM a graduate of YouTube university....ahahhaaaaa
From a half of a pig split down the backbone, there are 3 "primal" cuts....the front primal cut is between the 4th and 5th rib counting back from the head has the front leg/shoulder, etc. The next primal is the center section containing the rest of the ribs, the back loin, etc. The last primal on a side is the back section of the back leg, where the large ham comes from.
Here is a pic of that center primal....a whole loin including the belly which is what makes up bacon. This pic is looking at the top of the backbone, the right side is the front end of the pig, the left the back leg.
Same loin section, viewed from the end where the front primal is separated. Look under the ribs and you can sorta recognize that 'bacon look' in this cross section cut
Here is the other end of that same loin primal, removing the 'tenderloin' that lays inside the backbone. On a cow, that is often left intact and when steaks like Porterhouse or T-bone are cut, that portion is the smaller pc of meat to the side of the T in the bone. You could do the same to a pig, but it would make a heck of a big pork chop, and is traditionally cut out hole like I'm doing in the pic. We then slice it into thin cross pcs for frying or left whole as a very tender roast if big enough.
Once that's removed, I saw down the ribs couple inches below the top of the spine and cut out the whole top loin. That can be deboned with knife to make a whole, boneless loin you cut into chops or roasts + "baby back" ribs you get from the leftover short spine/rib pc. I usually leave my loin whole, and saw out chops with bone in, cook on the grill, and the dogs enjoy the bone.
Bone in chops + roasts from the "sirloin" end which is the end toward the back.
What you're left with is the belly section with the rest of the ribs still attached. You work the knife between the ribs and belly, filleting out the "spare" ribs as a whole plate, leaving the boneless belly section to be trimmed up and cured into bacon.
