Roquefort-Sherry Mayonnaise
["2 egg yolks", "1 Tbsp. Dijon-style mustard", "2 Tbsp. sherry vinegar", "1 1/2 c. vegetable oil", "1 c. crumbled Roquefort cheese", "salt and freshly ground black pepper to taste"]
["Process the egg yolks, mustard and vinegar in a food processor or blender just to combine, about 30 seconds. With the machine running, pour the oil in a thin steady stream through the feed tube to make a thick mayonnaise. Add Roquefort and process just until combined (not smooth). Season to taste with salt and pepper. Makes about 3 cups."]
