Peeled king prawns

Peeled prawns, usually skewered so they can be turned together. Faster than shell-on and far less forgiving.

What it is

Form: Shelled
Typical weight: 12–25 g
Typical thickness: 15–25 mm
Cut: Not a cut of anything

Why it behaves as it does

Without the shell there is nothing between the flesh and the fire, so a peeled prawn cooks quickly and dries out quickly after that. Skewering is near-universal and is a handling solution rather than a cooking one: it lets a dozen prawns be turned as a unit and stops them rolling to one face or dropping through the bars.

When is it done?

When it goes wrong

It came out tough: Prawns, scallops, squid, lobster or octopus came out rubbery — 3 distinguishable causes.
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 peeled king prawns, and BBQHQ does not invent a distinction they do not make.
