These elegant oysters with champagne vinegar mignonette offer a sophisticated start to any dinner party. By lightly grilling the oysters until the butter sizzles and the edges just begin to curl, you enhance their natural sweetness while maintaining a delicate texture. The sharp, shallot-infused vinegar dressing provides a bright contrast to the rich butter, while a garnish of tiny grapes adds a refined burst of flavour.
As a diabetes-friendly appetiser, this dish is naturally low in carbohydrates and high in essential minerals.

Serve these warm as a luxurious light bite or a healthy, impressive seafood first course.

Pinch of coarsely ground black pepper
Pinch of sugar
1 teaspoon finely chopped fresh flat-leaf parsley
1 1/2 cups kosher or other coarse salt
1/2 dozen small oysters, such as Kumamoto or Prince Edward Island, shells scrubbed well and oysters left on the half shell, their liquor reserved and oysters picked over for shell fragments

How to make Oysters with Champagne-Vinegar Mignonette
Stir together vinegar, shallot, pepper, and sugar and let stand 30 minutes.
Preheat grill.
Spread 110g salt in an 8- to 10-inch flameproof shallow baking dish or pan. Arrange oysters on their shells in salt, then top each with a piece of butter.
Grill 4 to 6 inches from heat until butter is melted and sizzling and edges of oysters are beginning to curl, 1 to 2 minutes.
Stir parsley into mignonnette. Divide remaining 110g salt between 2 plates and arrange 3 oysters on each. Spoon 1/4 teaspoons mignonnette over each oyster and sprinkle oysters with grapes. Serve warm.
