BBQHQThe world of cooking over fire

Comparisons · Two cuts

Whole mackerel or Whole sardines

Two oily whole fish separated mostly by scale, where the smaller one cooks faster than most people allow for and is the one most often ruined.

What each one is

Whole mackerel

An oily whole fish, scored and grilled over direct heat. The oil is the cooking story: it renders, drips and flares.

Whole sardines

Small oily fish cooked whole and fast over a hot fire, and one of the few foods where blackened skin is the intended result rather than a failure.

Where they overlap

  • Both are the same food form, so the same safety rules apply to each.

What actually differs

Typical weight250–450 g60–120 g
Typical thickness

Thickness governs timing more than weight or cut name does — Weber's own chart roughly triples the time between a one-inch and a two-inch steak.

What BBQHQ's evidence gives for time

Windows from the cooking profiles, at the conditions each profile states. They are not comparable to the minute — the profiles differ in cooker and configuration — and are shown to give the scale.

What tends to go wrong

From BBQHQ's troubleshooting index. Choosing between two cuts is partly choosing which failure you would rather risk.

Can one stand in for the other?

Workable, once you change the cook

You can use one for the other. The cook changes, and the changes are below — do not carry the timing across unaltered.

What has to change

  • They are not the same thickness, and thickness moves timing more than weight or cut name does. Expect the window to move substantially, and probe rather than transferring the time.
  • BBQHQ's evidence gives these two materially different cooking windows, so the time moves even where the method does not. Take the window for the one you are actually cooking and probe towards it.
