Picnic shoulder

• 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 us 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

Picnic shoulder, or Arm shoulder (US), Picnic roast (US) depending where you are.

If that draws a blank

Ask for forequarter, lower — the muscle is Triceps brachii (lower), Brachialis.

What to specify

Typical weight is 3.5–5.5 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.

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.

  Workable, once you change the cook

  The lower arm half of the front shoulder, IMPS 405. In the UK it is not usually separated from the rest of the shoulder, so there is no distinct British name for it.

  • Around 10.2 lb on a 250 lb hog, marginally larger than the Boston butt.
  • UK butchery does not routinely make this split, so the distinction has no British retail existence.

  What differs

  • Around 10.2 lb on a 250 lb hog, marginally larger than the Boston butt.
  • UK butchery does not routinely make this split, so the distinction has no British retail existence.

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.
