MAYONNAISE made with a food processor
1 egg yolk, 1 tsp. white mustard, 1 tsp. wine vinegar
salt and pepper 1 cup oil
Put egg yolk, mustard, pepper, and salt in the food processor bowl fitted with emulsufing disc. Switch on at minimum speed. When mixture is homogeneous slowly add oil in a continuous stream. Add vinegar at the end and run for a few seconds at maximum speed.
I thought every one who uses a food processor would be interest in this recipe.
