Peel the baby potatoes and the parsnip.
Roughly dice the potatoes (if necessary) and the parsnip. Put everything into the Cristel roaster, sprinkle with a dash of olive oil, season with salt and pepper.
Cook in oven at 375°F for approximately 10 minutes.
In the meantime, prepare the langoustine tails, split them in two with a knife and place them on the grill, season with salt and pepper, smear with butter, add a little lime zest, and a few pink peppercorns.
Gently take the vegetables out of the oven, place the grill on top, and return to the oven at 200°C for approximately 10 minutes. The langoustine tails must be nice and red, the meat nice and white, and the vegetables nice and tender.
Serve with a few sprigs of fresh dill or fennel and a little fresh lime zest. Bon appétit!
