Balsamic Vinegar Mayonaise
2 large egg yolks
the juice of 1/2 a lemon or to taste
1-2 tblsp Venturi-Schulze balsamic vinegar
1 tsp Dijon mustard
enough vegetable oil to make a thick mayonnaise (1 to 2 cups)
salt and white pepper to taste
Put the egg yolks and the mustard in a bowl and whisk thoroughly together. Start adding the oil drop by drop at first, then in a stream as you keep beating with the whisk. When you have a very thick sauce, the consistency of sour cream or thicker, add the lemon, the balsamic vinegar and the salt and pepper. Beat again until smooth. Whisk in more oil if the sauce is too thin or runny.
