Pork shoulder

• Pork shoulder (blade)

  Forequarter, upper · high use · connective tissue: high

  The upper part of the front shoulder, with heavy intramuscular fat and collagen. The classic candidate for a long cook to a texture endpoint rather than a temperature one. IMPS item 406 in the US, where it is called the Boston butt.

  Muscles: Triceps brachii, Supraspinatus, Infraspinatus

• Pork arm shoulder (picnic)

  Forequarter, lower · high use · connective tissue: high

  The lower arm portion of the same front shoulder, IMPS item 405. Distinguishing it from the blade end is what makes 'Boston butt' a meaningful term rather than a regional synonym for shoulder — and UK butchery, which does not routinely make the split, has no word for either half.

  Muscles: Triceps brachii (lower), Brachialis

Named the way uk butchery names it. If the counter does not recognise the name, the anatomy is the fallback: ask for the cut by where it comes from.

What to say

Pork shoulder.

If that draws a blank

Ask for forequarter, upper or forequarter, lower — the muscle is Triceps brachii, Supraspinatus, Infraspinatus.

What to specify

Typical weight is 2.0–4.0 kg.

Derived from how hard the muscle works and how much connective tissue it carries, which is the pairing that decides whether a cut wants a fire under it or beside it. BBQHQ does not rank cuts and does not name a best one.

• High connective tissue: this wants long, low, indirect heat. Collagen converts to gelatine slowly and well above any safety endpoint, so the cut is tough until it has had the time and tender afterwards. Cooking it fast makes it worse, not quicker.
• A hard-working muscle, which is why it carries the tissue it does and why it rewards patience.

BBQHQ holds cooking evidence for this cut as pork shoulder, pork shoulder steak.

A substitute is not the same as an equivalent. These are graded, because “yes, use that instead” is the answer that ruins dinners: most real substitutions work only once something about the cook changes.

• Boston butt

  Workable, once you change the cook

  The Boston butt is the UPPER half of the front shoulder, IMPS 406, and the picnic is the lower arm half, IMPS 405. A UK 'pork shoulder' may be either or both, so ask for the blade end if you want the American pulled-pork cut.

  • US butchery routinely splits the shoulder into butt and picnic; UK butchery often does not.
  • A Boston butt runs around 4.3 kg on a 250 lb hog; UK shoulder joints are commonly sold at 2–4 kg.
  • Asking for 'butt' in the UK will not be understood as a shoulder cut.

• US butchery: Overlapping cut

  Boston butt

  The Boston butt is the UPPER half of the front shoulder, IMPS 406, and the picnic is the lower arm half, IMPS 405. A UK 'pork shoulder' may be either or both, so ask for the blade end if you want the American pulled-pork cut.

  What differs

  • US butchery routinely splits the shoulder into butt and picnic; UK butchery often does not.
  • A Boston butt runs around 4.3 kg on a 250 lb hog; UK shoulder joints are commonly sold at 2–4 kg.
  • Asking for 'butt' in the UK will not be understood as a shoulder cut.

The UK side of these mappings rests on AHDB’s published cutting specifications, which BBQHQ has read. The US side does not: USDA’s Institutional Meat Purchase Specifications and the Beef Checkoff cut pages both refuse automated access, so no mapping here reaches “same cut” across two butchery systems.
