Recipe: Langoustines with garlic-and-herb butter and Dijon mayonnaise

Patricia Martin shows us how to make this showstopping dish with a Scottish favourite.

Call it what you will – langoustine, Dublin Bay prawn, Norway lobster or just plain scampi – Nephrops norvegicus is to many as good as it gets when it comes to quality shellfish. A delicate and exquisitely flavoured crustacean, it epitomises everything that a well-structured plate of fruits de mer should be.

Whether the mainstay of chargrilled harbour-side platters, the adornment of paella and zarzuela, gilded in lemon butter or simply served raw, with coriander, lime and olive oil, its sweet flesh is sure to enliven the tastebuds of the most hardened of connoisseurs.

The tide-harried waters of the Minch, that lonely strait of water separating the Scottish Highlands and Inner Hebridean Isles from North Uist, Lewis and Harris, is home to some of the finest examples of this underrated species. With creel fishing and bottom-trawling both playing a large part in harvesting langoustines, shellfishing has been a mainstay of these wild, gale-lashed isles for centuries.

Minch Langoustines

Although langoustine, native lobster and brown crab predominate in terms of landings, the variety of other shellfish species here in abundance (scallop, squat lobster, velvet crab, razor clam) is typical of a coastline royally served by a smorgasbord of planktonic life powered by the Gulf Stream.

Langoustines (prawns, to the local fishermen) are one of those species that now demand the combined effort of both trawlers and potters and whose daily landings are transported to European ports such as Vigo and Santander in Spain. However, with 80% of UK exports destined for that market, it’s small wonder that many of these little orange lobsters don’t make landfall in Britain.

minch langoustines

Serves 8


  • 80 medium, fresh and live Minch langoustines
  • New potatoes (lightly crushed with olives)
  • Green vegetables (steamed)

For the Dijon mayonnaise

  • 2 egg yolks
  • 1 tbsp Dijon mustard
  • 350ml groundnut oil
  • Juice of half a lemon

For the garlic-and-herb butter

  • 2 packs butter
  • 4 crushed cloves garlic
  • Fennel, parsley, lovage and chervil (a bunch of each)
  • Juice of 2 lemons


To make the Dijon mayonnaise, mix the egg yolks and mustard in a large ceramic bowl and gradually whisk in the oil, a drop at a time, until the mixture starts to thicken. As it does so, add the oil in a continuous stream, then season to taste with salt, pepper and lemon juice. Divide between eight ramekins and chill.

Next, melt the butter with the garlic and set aside for a while, before blitzing it together with the herbs and lemon juice, using a hand blender or a liquidiser.

Bring a large pan of salted water to a rolling boil and cook the langoustines in batches of eight – drop them into the boiling water, then cover with a lid. As soon as the water comes back to the boil – which only takes a few minutes – they’re cooked. Set aside and don’t worry about keeping them hot.

Arrange 10 langoustines on each plate and pour the garlic-and-herb butter over the top, then place a ramekin of Dijon mayonnaise alongside them and serve with the crushed new potatoes, olives and vegetables. Remember to provide finger bowls and extra napkins, as picking apart the butter-covered langoustines can be a messy business.
