Scallops and Black Pudding: The Scottish Pairing, and How to Sear a Scallop

Scallops on black pudding is the dish every Scottish restaurant with a west coast supplier puts on its menu, and it has been for long enough that it reads as a cliché. It survives because it is genuinely well built: sweet, delicate, expensive shellfish sat on something salty, peppery and crumbling, with the fat of the pudding doing the work a sauce would otherwise have to do.

It is also a twenty-minute dish that people ruin regularly, in three predictable ways.

Why the pairing works

A scallop is sweet, faintly mineral and very soft. On its own it needs salt, acid and fat or it reads as bland — which is why almost every scallop recipe reaches for butter, bacon, lemon or chorizo.

Stornoway black pudding supplies all three at once, plus a texture contrast the others do not: it is drier and more crumbly than the standard pork-fat pudding, because it is built on beef suet and a heavy load of oatmeal. It holds its shape under a scallop instead of collapsing into a smear, and the oatmeal grit against soft shellfish is most of the point.

Use the Stornoway one if you can get it — it is a protected name and the texture is the reason this version of the dish is better than the English one made with a softer pudding.

The three things that ruin a scallop

1. Wet scallops. Water on the surface has to boil off before the pan can brown anything, and by the time it has, the scallop is cooked through and rubbery. Pat them completely dry, on paper, and let them sit out of the fridge for fifteen minutes first.

2. A pan that is not hot enough. You want it shimmering. A scallop wants a hard, fast sear — around 90 seconds a side for a large king scallop — and a medium pan gives you a pale, tough one instead.

3. Moving them. Lay them down, leave them alone, turn once. Every nudge interrupts the crust.

A fourth, less common: crowding the pan. Scallops touching each other steam. Cook in two batches if you have to.

Wet-packed vs dry-packed — the buying rule that matters most

This is the one worth knowing before you spend the money.

Dry-packed scallops are shucked and sold as they are. Wet-packed scallops have been soaked in a phosphate solution, which makes them absorb water and gain weight. They look plumper and whiter on the counter.

They also cannot be seared, because the water comes straight back out in the pan. You will get a grey, weeping, boiled scallop no matter how hot the pan is, and you paid for the water by the kilo.

Ask your fishmonger which they are — a good one will tell you straight, and dry-packed is what a decent fishmonger stocks. Dry-packed scallops look slightly translucent and off-white rather than brilliant white, and they will not be sitting in liquid.

Hand-dived vs dredged

Worth understanding, since it appears on menus and changes the price sharply.

Dredged scallops are taken by towing a dredge across the seabed. Hand-dived scallops are collected individually by a diver. Hand-dived cost considerably more, are usually larger and cleaner, and are the ones sold with the diver's name attached in restaurants.

Both are west coast Scottish scallops and both can be excellent. Hand-dived is the premium product; dredged is what most of the catch is and what most of us cook.

The coral question

The orange roe attached to the white muscle. Keep it or remove it — this is a genuine matter of taste rather than a right answer. It is softer, richer and more strongly flavoured than the muscle, and it cooks faster, so it is easy to overdo. If you are unsure, cook a couple of each way.

Restaurants often remove it for appearance. Scottish home cooks usually leave it on.

Serving it

Twelve scallops on twelve slices of pudding serves four as a starter. Do not add much else: the pan butter with lemon in it is the sauce, and the plate wants nothing more than perhaps a few dressed leaves or a spoonful of pea purée.

As a main it wants a starch — but not much. Anything more than that and you have buried a very expensive shellfish under a dinner.

Frequently asked questions

Why do scallops go rubbery?

Overcooking, almost always caused by a pan that is not hot enough or by wet scallops that steam rather than sear. A large king scallop needs roughly 90 seconds a side in a shimmering pan and no more.

What is the difference between wet-packed and dry-packed scallops?

Wet-packed scallops have been soaked in a phosphate solution and absorb water, which makes them heavier and whiter but impossible to sear — the water comes out in the pan. Dry-packed scallops are sold as shucked. Always ask; only dry-packed will brown.

Why are scallops served with black pudding?

The pudding supplies salt, fat and a peppery, crumbling texture against a soft, sweet, delicate shellfish that would otherwise need a sauce. Stornoway black pudding suits it particularly well because its beef suet and high oatmeal content keep it firm under the scallop instead of collapsing.

Should you remove the coral from scallops?

It is a matter of taste. The orange coral is richer and stronger than the white muscle and cooks faster. Restaurants frequently remove it for presentation; many Scottish home cooks leave it on.

What is the difference between hand-dived and dredged scallops?

Hand-dived scallops are collected individually by divers; dredged scallops are taken by towing a dredge along the seabed. Hand-dived are more expensive, usually larger and cleaner, and are the ones named on restaurant menus. Both come from the same Scottish waters.
