What is the best way to store this dish?

In the refrigerator: Potatoes can be stored (unfilled) for up to 1 day. Langoustine tartare should be prepared fresh and consumed immediately. Creamy filling can be prepared separately and kept refrigerated for 1 day. In the freezer: Store the langoustine carcasses in a freezer bag – perfect for bouillon or bisque. Do not freeze baked potatoes or tartare. Reheating: Bake briefly in the oven again at 180°C (350°F) for 10–15 minutes (without the tartare). Add the tartare at the very end.

Can I also boil the potatoes instead of baking them?

Preferably not, as the roasting process creates that specific texture and full flavor. Boiling the skin softens it too much.

Which cheese should I use?

Go for a soft, spreadable Belgian cheese such as Brussels cheese, fresh goat's cheese, or mildly matured Herve.

Can I use shrimp instead of langoustine?

Yes, but use raw, fresh shrimp and prepare them into tartare in the same way.

What do I do with the langoustine carcasses?

Pop them in the freezer, ideal for using later for a homemade fish stock, soup or rich bisque.

Preparation method

How do you make this?

Baking potatoes

Preheat the oven to 195 °C (top and bottom heat).

Pierce each almond potato with a skewer. Rub them with clarified butter and sprinkle with sea salt.

Place them on a rack in the oven and roast them for 45 minutes, until they are soft inside.

Preparing prawn tartare

Clean the prawns: remove the shell and intestinal tract. Store the carcasses in the freezer – ideal for a future fish stock, soup, or bisque.

Cut the meat into small pieces and mix with the nut oil, a dash of lemon juice, salt, and pepper. Refrigerate.

Baking girolles

Brush any dirt from the girolles and cut them, together with the shallot, into fine brunoise.

Stew in butter with salt and pepper.

Making filling

Cut off the top of each baked potato, or carefully cut in half without cutting all the way through.

Scoop out some of the crumb from the potatoes without damaging the skin.

Mix this with the sour cream and the fried girolles.

Fill the potatoes again with this mixture and place in the oven for another 5 minutes.

Cut the spring onion into 5cm pieces, chop very finely and place in ice water so that they curl nicely.

Finishing and serving

Divide the potatoes among 4 plates. Garnish with a spoonful of sour cream, a quenelle of tartare, a few slices of girolle, and a sprinkle of pink peppercorns.

Serve immediately, lukewarm.

Use a potato with a nice, smooth skin, because you will be eating that too.
