2 egg yolks
1 c. sour cream
1 tbsp. horseradish
Juice of 1 lemon
1/2 tsp. salt
Dash of sugar
1/4 c. minced scallions (garnish)

Whisk egg yolks into sour cream. Add other ingredients. Heat very slowly over a double boiler, whisking periodically 8-10 minutes. This recipe nicely covers 4 servings of baked fish, baked potatoes, or steamed vegetables. Try it with an accompaniment of sweet and sour cabbage.
