Frothy Wine Dessert “Satou”

Serve 4
Ingredients
5 egg yolks
½ cup sugar
1 tablespoon finely grated fresh lemon peel
1 cup sweet white wine
Optional-2 tablespoon fresh raspberries
Preparation
Place the egg yolks, sugar and lemon peel in the top of an enameled or stainless-steel double boiler set over barely simmering water.
Beat with a whisk or an electric hand mixer for 15 to 20 minutes, or until the mixture becomes a thick custard. In a separate pan, quickly bring the wine to a boil.
Then pour it into the custard in a slow thin stream, beating all the while. Continue beating for another 10 minutes or so, until the mixed is thick enough to coat a spoon heavily.
Divide the composition to 4 individual dessert dishes and serve at once, while hot.
If you like, you can add raspberries just before serving.
