Instructions

1. Place the egg yolks, sugar, and wine into a metal bowl. Place the bowl over a saucepan of barely simmering water, making a double boiler. Whisk the mixture constantly until it foams and then becomes creamy and doubles in size, about 5 minutes. Mixture should be uncomfortably warm to the touch, but not burning. Remove the pan from the heat and whisk in the sour cream.;
