Langouste à la Vanille

What it really is

Comorian spiny lobster served with a delicately vanilla-scented sauce.

Lobster is cooked and served with a sauce built from its cooking juices, cream or butter and local vanilla. The preparation is associated with special meals; recipes differ in whether they use cream, coconut milk or a lighter stock-based sauce.

The name points to two defining elements: spiny lobster and vanilla. Vanilla should scent the sauce rather than make the dish taste like a dessert; the seafood remains the centre of the plate. How the sauce is built is not uniform in the available descriptions, so cream, butter, coconut milk and stock should not be treated as interchangeable mandatory ingredients. A cook may use the lobster juices as part of the sauce, but the exact technique is restaurant-specific. The dish is suited to a carefully described main course, with the lobster portion and sauce served together and starch or vegetables listed separately. Because crustacean allergen is inherent to the named seafood, it must be clear on a menu. Dairy or coconut declarations depend on the sauce actually used.

The lobster can be served whole or portioned, depending on size and service style. Keep the sauce description beside the seafood so guests can identify both the crustacean and the flavouring. If butter or cream is used, name the dairy; a coconut-based sauce needs a separate ingredient check.

The lobster should remain the focus and the vanilla should read as a savoury sauce aroma. Serve the sauce with the seafood rather than describing it as a sweet glaze; disclose butter or cream if used.
