Pork butt vs pork shoulder.
They are not two alternatives. "Pork shoulder" is the whole front leg and the meat above it, and USDA FSIS counts it as one of 4 pork primals (shoulder, loin, side, leg). The butt sits inside that primal, and so does the picnic below it. So a pork butt is a pork shoulder, but a pork shoulder is not necessarily a pork butt. Boston butt and pork butt are two names for that same upper half, and neither has anything to do with the back end of the pig.
The naming is historical, not anatomical. Both halves cook the same way and finish at the same temperature, which is why recipes use the words interchangeably and get away with it. What separates them is shape, skin and price, and the table below has the specifics on each.
Where they differ, and where they do not
| Pork butt (Boston butt) | Picnic shoulder | |
|---|---|---|
| Where it sits | Region 1 of the chart. The upper shoulder. Well marbled, forgiving, the pulled-pork cut. | Region 4 of the chart. The lower shoulder and upper foreleg. More connective tissue and skin than the butt; cheaper; smokes the same way. |
| Tenderness and richness | Tenderness 2/5. Richness 4/5. | Tenderness 2/5. Richness 3/5. |
| Best methods | Both: smoke, braise | |
| Finish | Both: bone slip, 195 to 205 F (craft) | |
| Planning time | Pork Board: about 1 hour 15 minutes per pound. 8 to 14 hours for a full butt at 225 to 250 F. Approximate. | Pork Board: about 1 hour 15 minutes per pound. Approximate. |
| Rest | 1 hour wrapped, above 140 F, before pulling. | 1 hour wrapped, above 140 F. |
| Slice | Pull, do not slice, once at the tenderness window. | Pull. |

Both cook to the same numbers
145 F (62.8 C), then rest at least 3 minutes before carving or consuming
Steaks, chops and roasts (whole muscle). Food thermometer in the thickest part, away from bone, fat and gristle, read before removing from the heat source. This is a food safety floor, not a preference. Where any other number on this page is lower, this one governs.

195 to 205 F, bone slip
For pulled pork, backyard convention finishes shoulder at 195 to 205 F when the bone slips clean and the meat shreds. The National Pork Board's own smoking table gives 185 to 190 F with the bone-slip test. Both are above the 145 F minimum; the difference is texture, and Pit Log shows both.
Which one to put in the cart
For pulled pork, buy the butt. It is squarer, easier to trim, and the blade bone gives you the bone slip test that tells you when it is done. Take the picnic if it is cheaper or you want the skin for crackling, and expect to spend longer trimming. A label reading "whole shoulder" is both halves together, which is a long cook and a lot of meat. Either way the safety floor is 145 F and the tenderness comes much later.
- Boston butt (bone-in or boneless). bone slip, 195 to 205 F (craft). 6 to 9 lb. Bone-in holds shape and gives the bone-slip test.
- Pork shoulder steak (blade steak). Your doneness, 145 F + rest USDA floor. St. Louis backyard classic. Grill to 145 F plus rest, or cook long until tender; both are legitimate.
- Country-style ribs (shoulder end). bend test, 190 to 203 F (craft). FSIS lists country-style ribs under the loin; many are cut from the blade end of the shoulder. Not true ribs.
- Picnic roast (arm picnic). bone slip, 195 to 205 F (craft). Skin-on picnics: score or remove the skin so smoke and rub reach the meat.
- Whole shoulder (butt plus picnic). bone slip, 195 to 205 F (craft). Whole-hog-style cook, 14 to 20 lb. Long day.
- Fresh hock. bone slip, 195 to 205 F (craft). Smoke 2 to 3 hours, then simmer in the pot.
- Smoked hock (check cooked or uncooked on the label). 165 F (USDA). Cooked: reheat to 165 F. Uncooked smoked: 145 F plus rest, then simmer for tenderness.
- Where the probe goes. Insert the thermometer into the thickest part of the food, not touching bone, fat or gristle. For thin foods insert through the side. Check large or irregular pieces in several places. For a whole bird check the innermost thigh and wing and the thickest part of the breast.
- Colour is not doneness. Appearance and colour are not reliable indicators of safety or doneness. A burger can be brown and unsafe or pink and safe. Pork at 145 F can be pink. Smoked chicken can stay pink at the bone at 165 F.
Now cook it
