German Eggs in Green Sauce

This cold dish originated in Frankfurt and was reportedly one of the favorites of Goethe. It is frequently served with boiled potatoes, which are dipped into the sauce.

1/2 cup sour cream
1/2 cup yogurt
1/4 cup mayonnaise
Juice of 1 lemon
9 to 13 hard-boiled eggs, peeled
1 1/2 cups finely chopped fresh herbs (any combination
    of parsley, tarragon, chives, dill, or fennel greens)
1/2 teaspoon sugar
Salt and freshly-ground pepper, to taste

Combine the sour cream, yogurt, mayonnaise, and lemon juice. Finely chop one of the eggs and stir it into the mixture, along with the herbs, sugar, salt, and pepper. Spoon the sauce onto a serving platter or individual plates. Slice the remaining eggs in half and arrange them on the sauce.

Serves 4 to 6.
