Makes 6 portions.
8 egg yolks
3/4 cup granulated sugar
1/3 cup Marsala wine
Mix ingredients together in the top part of a double boiler* and cook over rapidly boiling water, whisking constantly until mixture doubles in bulk and thickens.
Remove from heat and continue whisking for about a minute.
Pour mixture warm over fresh berries, serve by itself in tall glasses, or chill and use as a sauce for berries.
*If you haven't got a double boiler, do what I do: use a bowl that fits tightly into the mouth of a cooking pot so that little or no steam can escape, and hold it tight with an oven mitt-clad hand while whisking with the other hand.
If I make this, how can I use the egg whites, besides making a ton of meringue?
