For the salad peel the cucumber. Clean and wash the radishes. Slice both into thin slices. For the vinaigrette season lemon juice with salt, pepper and 1 pinch of sugar. Fold in the oil.
Dab pork tenderloin dry and cut into 3-4 mm thin slices. Put the starch in a plate. Turn the fillet slices in it. Heat clarified butter in a large pan. Fry the fillet slices in it in 2-3 portions per side for about 2 minutes.
Season with salt and pepper and remove. Deglaze the roast with cream and 200 ml water. Bring to the boil, simmer a little until the sauce thickens slightly.
Wash the herbs and shake dry. Pluck the chervil leaves and chop them coarsely. Cut chives into fine rolls. Mix cucumber, radishes and chives with the vinaigrette. Season salad with salt and pepper.
Season the cream sauce with salt and pepper and warm the fillet briefly. Sprinkle chervil over the meat and eat the salad with it. Baguette tastes good with it.
