Pork spareribs

The full rack off the belly, and the food in this catalogue where two competent publishers disagree most sharply: Weber gives 3–4 hours and the National Pork Board 5–7, with no overlap at all.

What it is

Form: Bone-in joint
Typical weight: 1.1–1.6 kg
Typical thickness: 25–40 mm
Cut: Spareribs

Why it behaves as it does

BBQHQ does not resolve that disagreement, because it cannot: Weber states a rack weight and no temperature, the Pork Board states a temperature and no weight, so the axis they differ on is not identifiable from what they publish. Cook to the bend and the pull-back, not to either clock.

When is it done?

Food-safety endpoint

Food Standards Agency
The Food Standards Agency names pork alongside chicken and minced products as food that should not be served pink or rare, because bacteria can be present within the meat rather than only on its surface. A whole cut of pork is therefore not covered by the permission the same guidance gives to steaks.
The rule and its source
The same Food Standards Agency guidance names pork and chicken, with minced products, as foods that should not be served pink or rare — placing whole cuts of pork on the opposite side of the sentence from whole cuts of beef and lamb.
Well established
- Food Standards Agency — States this directly
  “other meats, like chicken and pork, as well as minced meat products such as burgers, kebabs and sausages should not be served pink or rare as bacteria can be in the meat”
  What it covers:
  Applies to England, Northern Ireland and Wales, as the document states.
  Pork is named, as a species, on the restricted side. This is the sentence that stops the red-meat permission being read as covering whole cuts generally: a pork loin is a whole cut and is excluded by name.
  Shape:
  Again no figure. The FSA's numerical endpoint — 70 °C for two minutes or an equivalent — is published in its business guidance and modelled separately; this sentence is a form rule and is recorded as one.

USDA Food Safety and Inspection Service
In the United States, whole cuts of beef, pork, lamb and veal — steaks, chops and roasts — should reach 145 °F (63 °C), followed by a rest of at least three minutes before carving or eating.
- 63 °C (145 °F) — measured at the centre of the thickest part, away from bone and fat.
The rule and its source
In the United States, whole cuts of beef, pork, lamb and veal have a safe minimum internal temperature of 145 °F (63 °C), followed by a rest of at least three minutes.
Well established
- United States Department of Agriculture, Food Safety and Inspection Service — States this directly
  “Cook raw beef, pork, lamb and veal steaks, chops, and roasts to a minimum internal temperature of 145 °F ... allow meat to rest for at least three minutes”
  Form:
  Whole cuts only. Ground meats are covered by a separate, higher figure.
  The three-minute rest is part of the safety requirement, not only a quality step.
  How it was measured:
  As measured with a food thermometer before removing from the heat source.

Health Canada
In Canada, pork pieces and whole cuts — bone-in chops, boneless loin chops, rib roast and loin roast — should reach 71 °C (160 °F), and fish 70 °C (158 °F). Shellfish and crustaceans are 74 °C. No rest interval is attached to any of these.
- 71 °C (160 °F) — measured at the centre of the thickest part.
- 70 °C (158 °F) — measured at the thickest part of the fillet.
The rule and its source
In Canada, pork pieces and whole cuts should reach 71 °C (160 °F), and fish 70 °C (158 °F). No rest interval is attached to either.
Well established
- Health Canada — States this directly
  “Pieces and whole cuts, for example, bone-in chops, boneless loin chops, rib roast, loin roast 71 160 ... Fish 70 158”
  The sharpest disagreement in the catalogue between two neighbours. Canada gives a pork chop 71 °C; USDA FSIS gives 63 °C with a three-minute rest. That is eight degrees and a rest interval between two countries whose supermarkets sell the same cuts. Fish diverges too: 70 °C against the American 63 °C.
  Canada's chart attaches no rest interval to any row.

Texture endpoint — how you actually know

Bend test: the rack cracks on the surface and the bones have pulled back

Lifted with tongs a third of the way along, the rack droops and the surface cracks. The meat has shrunk back from the ends of the bones by roughly a centimetre. This is what BBQHQ can offer instead of a time, and it is what both publishers' figures are approximating.

How long it takes

Pork spareribs, smoked

Estimated cooking window

Sources disagree. Two competent publishers give 3–4 hours and 5–7 hours for the same cut and broadly the same method, with no overlap. BBQHQ holds no basis for preferring either and will not average them.

What this rests on

BBQHQ publishes no single window — the sources disagree.

Observations: 3
Documents: 3
Publishers timing this cook: 2

National Pork Board · Weber-Stephen Products LLC

Also on this page, supplying endpoints or doneness rather than timings: United States Department of Agriculture, Food Safety and Inspection Service. They are not a second opinion about how long the cook takes.

Why confidence is not higher

The sources give times that do not overlap.
At least one source does not state the cooker temperature.
No source states the weight of the food.

Sources disagree

Weber: 3–4 hours indirect low for a 2½–3½ lb rack, no cooker temperature stated. National Pork Board: 5–7 hours at 225–250 °F, no rack weight stated. No overlap, and no way to tell from the published figures whether the difference is the temperature, the rack, or a different idea of when ribs are done.

How the sources were combined

BBQHQ PUBLISHES NO TIME FOR THIS COOK, AND THAT IS THE ANSWER. Weber gives 3–4 hours indirect low for a 2½–3½ lb rack; the National Pork Board gives 5–7 hours at 225–250 °F. The windows do not touch at any point. Both publishers are competent, both describe low, slow, indirect cooking, and each states exactly the variable the other omits — Weber a rack weight and no temperature, the Pork Board a temperature and no weight — so the axis on which they differ cannot be identified from what either publishes. A union would give 3–7 hours, which is not a window but a shrug. A mean would be five hours, supported by nobody. The disagreement is preserved and the reader is told to cook to the bend test instead.

What makes the window as wide as it is

Sources disagree about this
Cookers hold temperature imperfectly
Weight varies within the range this covers
Individual animals and pieces differ

One open question tracked for this.

When it goes wrong

It came out dry: Ribs came out dry — 2 distinguishable causes.
It came out tough: Ribs came out dry — 2 distinguishable causes.
It caused flare-ups: Flare-ups — 2 distinguishable causes.
The sauce or coating burnt: The sauce or glaze burnt black — 2 distinguishable causes.

Also relevant to pork spareribs

Afterwards

Cooling, keeping and reheating what is left is general guidance for barbecue leftovers. Neither UK authority publishes anything specific to pork spareribs, and BBQHQ does not invent a distinction they do not make.

What we don't know about this

Two competent publishers give smoking times for this cut that do not overlap. BBQHQ reports the disagreement rather than averaging it, and cannot yet say which conditions differ.

What we know we’re missing records what was searched for each of these, and what would settle it.
