Shell the langoustine tails, removing the heads while leaving the last three tail rings intact for presentation.
Finely shred the white cabbage and blanch in salted boiling water until crisp-tender. Shock in ice water to cool and preserve texture.
Using a Parisienne spoon, form balls from the carrots, zucchini, and potatoes.
Finely chop the chervil leaves.
Pare and cut the ginger into a fine brunoise dice.
Sear the langoustine tails quickly on both sides in hot olive oil. Drain on absorbent paper towels.
Warm the cabbage in a touch of aromatic oil, season with salt and freshly ground pepper, and mound into the base of each cassolette dish.
In a small saucepan over low heat, gently warm aromatic oil with seasoning, ginger, lightly crushed pink peppercorns, and chopped chervil.
Arrange the seared langoustine tails atop the cabbage. Spoon the infused oil mixture over the shellfish and add the vegetable balls, also lightly coated in the aromatic oils.
