Corn on the cob
The only vegetable in the catalogue with a retrieved timing, and it turned out to have a variable nobody looks for: the husk roughly doubles the time and changes the mechanism from grilling to steaming.
What it is

When is it done?
Food-safety endpoint
BBQHQ holds no food-safety rule for this food. We are not showing you another jurisdiction’s figure in its place — check your national food-safety authority.
Texture endpoint — how you actually know
Kernels tender and steamed, with little colour
A kernel gives easily under a thumbnail. Corn in the husk does not take char, and that is the trade this preparation makes rather than a sign of it being underdone.
How long it takes
Corn on the cob, in the husk
Estimated cooking window
25 min–30 min
Moderate confidence
Why this is a range, not a number
- Cookers hold temperature imperfectly
- Individual animals and pieces differ
Cook to the endpoint, not to the clock. The window tells you when to start checking.
What this rests on
BBQHQ publishes a window for this cook.

Why confidence is not higher
- At least one source does not state the cooker temperature.
How the sources were combined
ONE SWEETCORN PROFILE SPLIT INTO TWO, AND HALF A CONFLICT DISAPPEARED. The corn refusal had been classified as a modelling limit: one profile spanning husk-on and husked, no way for a reader to say which they meant, and the two figures reported as though the publishers disagreed. They do not. Weber gives corn in the husk 25–30 minutes and the same corn husked 10–15, on one chart row, because a husk traps moisture and the corn steams rather than grills — that is a preparation difference, and preparation is now a dimension the chooser can ask about. THE SECOND PUBLISHER GIVES THE SAME FIGURE: North Dakota State University Extension prints 'Corn on the cob: peeled, 10 to 12 minutes; in husk, 25 to 30 minutes'. Two independent publishers, one a manufacturer and one a land-grant extension service, 25–30 minutes each. The exact agreement is worth stating rather than glossing, because an identical range invites the suspicion of restatement: NDSU attributes nothing, and the rest of its twelve-vegetable list does not track Weber's chart — its peeled corn figure is 10–12 where Weber's is 10–15, and its whole bell pepper figure has no Weber counterpart at all. What NDSU adds beyond a second voice is that it draws the husk distinction ITSELF, in one line. BBQHQ had to infer that distinction from two publishers who each described one side of it; this one controls the variable.
What makes the window as wide as it is
- Cookers hold temperature imperfectly
- Individual animals and pieces differ
Corn on the cob, husked
Estimated cooking window
Sources disagree. Weber 10–15 minutes, North Dakota State University Extension 10–12, Iowa State University Extension 4–5, for the same husked cob over medium heat. Watch the kernels rather than the clock: they colour and blister where they touch the bars, and Iowa State's advice is to take produce off before it is soft because it goes on cooking after it leaves the heat.
What this rests on
BBQHQ publishes no single window — the sources disagree.

Why confidence is not higher
- The sources give times that do not overlap.
- At least one source does not state the cooker temperature.
How the sources were combined
THE HALF OF THE CORN CONFLICT THAT SURVIVED THE SPLIT, and it is a real one. All three of these describe a cob with the husk and silk off, cooked directly on the grate over medium heat: Weber gives 10–15 minutes, North Dakota State University Extension gives 10–12, and Iowa State University Extension gives 4–5, turning frequently. Disjoint figures, independent publishers, and no stated condition between them beyond a heat all three call medium. The preparation dimension exists precisely so this comparison can be made honestly, and the honest result is that it is still a disagreement. A THIRD PUBLISHER IS ADDED AND DOES NOT GET A VOTE. NDSU's 10–12 overlaps Weber and remains disjoint from Iowa State, so the tally is two against one — and this catalogue unions and separates rather than counting heads. A majority is not a reconciliation, and adopting Weber's figure because a second publisher happened to agree with it would settle a disagreement by arithmetic on publishers rather than on evidence. The NDSU row is here because its husk-on row corroborates the other corn profile and a document is admitted whole; taking the useful half and quietly leaving this one is the single bias no check here can catch. No window is published.
What makes the window as wide as it is
- Cookers hold temperature imperfectly
- Individual animals and pieces differ
When it goes wrong
- It stuck to the grate
- Food sticking to the grate — 2 distinguishable causes.
Afterwards
Cooling, keeping and reheating what is left is general guidance for barbecue leftovers. Neither UK authority publishes anything specific to corn on the cob, and BBQHQ does not invent a distinction they do not make.
