Mayonnaise Sauce
from the Vegetarian Epicure

This mayonnaise is used in Holiday Vegetable Salad from the Vegetarian Epicure cookbook, but is excellent for any potato salad. It is made with hard-boiled eggs mixed with oil, lemon juice and sour cream instead of mayonnaise.

2 hard-cooked eggs (egg yolks only, add the whites to the vegetable salad)
4 Tbls. olive oil
2 Tbls. lemon juice
1/2 tsp. sugar
1/4 c. sour cream (more if desired)
1/2 Tbls. prepared mustard
salt & pepper

Blend the egg yolks with the olive oil, lemon juice, and sugar until smooth. Add the sour cream, mustard, salt & pepper and blend again. It should be thick and pale in color.
