Eating them is an exercise in history; the recipe has never changed in the 230 years since their invention, and it has only ever been passed to the succeeding pâtissier of the Maison des Sœurs Macarons. "The recipe and the secret are passed on orally, they've never been written down, and, in the contract with the new pâtissier, both sides swear to never teach the making to anybody else," explained Genot. "The owner of the pâtisserie is the only one who makes the macaron, alone and away from prying eyes."
