With spring just around the corner, so is Jour du Macaron!

On Wednesday, March 20 macaron lovers in Paris and throughout France are invited to indulge in the tasty treat while supporting a worthy cause.

Here’s how it works: participating pâtisseries are offering visitors free macarons on March 20. In turn, the stores will be accepting donations for Vaincre la mucoviscidose, a non-profit association that helps those who suffer from cystic fibrosis.

In Paris, the participating pâtisseries for this 8th edition are Sadaharu Aoki, Laurent Duchêne, Pierre Hermé, Jean-Paul Hévin, Arnaud Larher, Christophe Roussel and Dalloyau. Numerous other Relais Desserts member pâtisseries throughout France will also be taking part.

First held in 2005, Jour du Macaron was created by Pierre Hermé in the aim of creating a gourmand event in support of charities, notably those that help children afflicted by rare diseases and other ailments.
