In a food processor, combine egg yolks,mustard, anchovies and garlic. Blend until smooth. With the machine running, slowly add the oil. Add the lemon juice, Worcestershire sauce and vinegar, salt and pepper. Pour over romaine chopped lettuce and add croutons. Toss well. Add grated cheese and enjoy. This makes enough dressing for 4 stalks of Romaine lettuce, cut in approximately 1 inch square pieces. The croutons absorb much of the dressing and the cheese does as well.
