Wine Custard (Zabaglione)

Eat this thin custard freshly made and warm. It is also a wonderful sauce for fresh berries, plain cake or fruit-filled cr?pes.

4 egg yolks
1 egg
1/3 cup granulated sugar
1/3 cup Marsala wine or sherry
Dash of salt

Beat egg yolks and egg in small mixer bowl on high speed until thick and lemon colored, about 3 minutes.

Gradually beat in sugar, scraping bowl occasionally. Beat in wine and salt on low speed. Pour mixture into top of double boiler. Add enough hot water to bottom of double boiler so that top does not touch water. Cook over medium heat, stirring constantly, until slightly thickened, about 5 minutes. The water in the double boiler should simmer but not boil.

Remove from heat. Serve immediately.

Yields 4 to 6 servings.
