Makes 4 medium ramekins
From the Best Recipe
3 oz dark chocolate
1 oz butter (salted)
1 teaspoon vanilla extract
1 tablespoon orange liqueur
grated zest of half an orange
2 eggs, separated
1 tablespoon sugar
4 fl oz heavy cream (chilled)
Method:
Melt the chocolate in the microwave on 50% power.
Add the butter and whisk in, if it doesn't melt, microwave for another 15-30 seconds on 50% power
Add the vanilla, orange liqueur, and orange zest
Whisk in the egg yolks, one at a time
Whisk the egg whites to soft peaks, add the sugar gradually whilst whisking, take back to soft peaks
Stir in 1/4 of the whisked egg whites, add the rest and fold in gently
Whisk the cream to soft peaks and gently fold it in to the rest of the mixture.
Spoon or pour into ramekins, and refrigerate for at least 2 hours.
Notes: The orange zest fixes the flavor, but detracts from the smooth texture. Try orange oil?
