Mix the egg yolks with the oil. To begin with, add the oil drop by drop and whisk with a whisk. Later you can also add the oil in a fine stream and stir vigorously.
Peel the garlic and chop it up with a blender, it`s the fastest.
Add the yogurt, pepper, vinegar, Worcestershire sauce, mustard and salt to the mayonnaise (although I don`t use the mustard and salt too sparingly). Finally add the garlic and mix in.
If possible, let steep in the refrigerator for a few hours before you can eat them.
