Huîtres au sabayon de Champagne is one of my favourite hot appetisers - perfect with a glass of Champagne.
- 50 g butter, melted
- 1 medium shallot, finely chopped
- 12 small mushrooms, finely chopped
- salt and freshly ground black pepper
- 12 freshly opened oysters
- 80 ml Champagne
- 2 egg yolks
Oven temperatures are for conventional; if using fan-forced (convection), reduce the temperature by 20˚C. | We use Australian tablespoons and cups: 1 teaspoon equals 5 ml; 1 tablespoon equals 20 ml; 1 cup equals 250 ml. | All herbs are fresh (unless specified) and cups are lightly packed. | All vegetables are medium size and peeled, unless specified. | All eggs are 55-60 g, unless specified.
Heat 20 g of the melted butter in a small pan. Stir in the shallots and cook over low heat for 2 minutes. Stir in the chopped mushrooms and cook, stirring occasionally, for about 10 minutes until most of the moisture has evaporated. Season with salt and pepper.
Preheat the oven to 250°C.
Remove the oysters from the shell and put the shells aside on an oven tray. Place the oysters in a small ovenproof pan with 50 ml of the Champagne and bring to a low simmer. Very gently stir in the oysters and turn off the heat.
Place the egg yolks in a bowl and mix with the remaining 30 ml of Champagne. Place the bowl over a bath of simmering water (bain-marie) and beat the yolks and champagne until light and fluffy. It takes a few minutes and the egg must not scramble.
Remove the bowl from the heat, slowly whisk in the remaining melted butter and season with salt and pepper.
Spoon a little mushroom purée into the 12 clean oyster shells. Top with a drained oyster, then coat the oysters with the Champagne sauce. Place the oysters in the hot oven for a few minutes until the sauce has lightly browned. Serve immediately.
