2 eggs, beaten
1 tbsp. flour
2 tbsp. butter
1/2 c. vinegar
1 c. sugar
Salt & pepper to taste

Put butter in saucepan, melt and add all other ingredients. Bring to a boil until thick. Cool. I always add a little mayonnaise and make it a little thinner. I also add chopped onions and celery while it's still hot. Cover top with hard cooked eggs.

This is also good when making macaroni salad (I don't put the eggs on top of macaroni but I do add diced tomatoes and cheese).
