There is only one authentic macaron in all of France. It is from the city of Nancy in the Lorraine region. While many pastry shops in Nancy and throughout France will sell macarons, the original and authentic macarons recipe is from the Macarons des Soeurs, the nuns who created this almond cookie in 1793.
It remains a secret recipe to this day. While the basic ingredients are simple, egg whites, ground almonds and sugar, which are piped into circles on a baking sheet, getting a perfect cookie, light as air with a thin crunchy crust and a moist inside is tricky. So is getting the cookie to crackle just right. You'll probably notice that most macarons sold outside of Nancy do not have the characteristic cracks. The Macarons des Soeurs are never stuffed or sandwiched with ganache like the macarons Ladurée later created.
The Macarons de Nancy are the type of macarons I ate when I was living in France and they are one of my favorite treats. They are often imitated, but never equaled.
