Help preparing shrimp and cocktail sauce

Gotcha. I think we’d just call that dish ‘garlic prawns’. Scampi to us is always deep fried (was a popular pub dish in the 70s & 80s) - and usually does use langoustines because they are plentiful in Scotland, and Brits don’t eat them much in their natural state (too scared of the claws, presumably). Most get shipped off to Spain and France, where they don’t hold with such squeemish nonsense.
