Thinly slice the meat from the salmon tail, proceeding with small horizontal cuts.
Arrange the slices on a tray, season with oil, salt, pepper and a few drops of lemon juice and leave to rest in the refrigerator.
Meanwhile, season the ricotta with the chopped pistachios, salt, pepper and oil.
Take the salmon carpaccio, place a small amount of filling on each slice and roll them up to form rolls. Complete the dish with a drizzle of oil and plenty of balsamic glaze.
