For the vinaigrette, dissolve the salt and sugar in lukewarm water, then leave to cool. Add the balsamic vinegar and mix well, add pepper. Finally add the olive oil and mix carefully with the vinegar solution.
Serve the lamb`s lettuce and mix in the vinaigrette.
Tip: I also like to prepare a larger amount. This can be kept for a few days in the refrigerator if it is tightly closed. For the right flavor, take it out of the refrigerator half an hour before serving.
