Mix lemon juice with red wine vinegar, balsamic vinegar and mustard. Add salt. Press the garlic, stir in, add the mustard and the sugar. Finally stir in the olive oil. Season to taste with pepper.
Makes a spicy salad dressing that is very refreshing thanks to the lemon juice. Tastes particularly good with colorful salads, I always use green lettuce, tomatoes and chopped mushrooms.
