What British seafood sauce actually is

In Britain, seafood sauce means a Marie Rose style sauce: mayonnaise-based, pale pink, softly spiced, with a little tomato and a hint of Worcestershire heat. It is creamy rather than sharp, and it is spooned over cold prawns on shredded lettuce to make a prawn cocktail, which was a fixture of British dining for decades and has never entirely left.

The 155g bottle is the standard size, because it is used in modest quantities on cold seafood rather than as an everyday table sauce.

Why this trips up American shoppers

The phrase "cocktail sauce" means something entirely different on each side of the Atlantic, and the gap is large enough to ruin a dish.

American cocktail sauce is a clear red sauce built from ketchup and prepared horseradish, sharp and pungent, served cold with shrimp. British seafood sauce is opaque, pink, creamy and mayonnaise-based, with only a background warmth. One is a vinegary condiment; the other is essentially a dressing.

Substituting one for the other does not work. If a British recipe calls for seafood sauce and you use the American product, you get a hot, thin, red mixture where the recipe expected a mild pink dressing. This is the single most common reason people import the British bottle rather than making do.

How to use it

The classic is prawn cocktail: cold cooked prawns, shredded iceberg lettuce, the sauce over the top, a dusting of paprika and a wedge of lemon. Beyond that it works in a prawn sandwich, with cold crab or smoked salmon, or as a dip for cold seafood generally.

It is mayonnaise-based, so refrigerate after opening and use it within the period stated on the bottle. It does not have the long open life of a vinegar-based sauce.

Frequently asked questions

Is this the same as American cocktail sauce?

No. American cocktail sauce is a red ketchup and horseradish mixture. British seafood sauce is a creamy, pink, mayonnaise-based Marie Rose style sauce.

What is Marie Rose sauce?

The British name for this style: mayonnaise with tomato, a little Worcestershire and seasoning. It is what goes on a prawn cocktail.

Is it spicy?

Only faintly. There is a background warmth rather than heat, which is one of the main differences from the horseradish-driven American version.

Does it keep?

Refrigerate after opening and follow the date on the bottle. Being mayonnaise-based, it does not keep as long as a vinegar-based table sauce.
