Rossini's "Glutton's Sauce" was created to celebrate the success of his "Barber of Seville" in Rome, after its initial premiere was met with boos. This recipe, featuring Provençal olive oil, English mustard, French vinegar, lemon, pepper, salt, and a touch of truffle, reflects the composer's playful spirit and love of good food. The truffle, considered the "Mozart of mushrooms," adds a touch of luxury and elevates the sauce to a culinary masterpiece. (Coll. UU.2/1)
