French macarons are thin, flavorful meringue cookies that are sandwiched together with some kind of filling. The meringues are what make the cookies unique. They have a smooth, crisp shell and a moist, chewy interior. They are made with egg whites and lots of ground nuts, which helps them to attain that chewy texture without drying out and becoming too crispy, like a simple meringue cookie made with just egg whites and sugar. The fillings can be almost anything that will stay between the cookies, from jams and preserves to caramel to buttercream frosting. I’ve even used Nutella to finish off a batch of macarons before. Although they can come in any size, macarons are typically small enough to be eaten in one or two bites.
Macarons are a French staple and if you happen to be in Paris, you’ll have no trouble finding them at most bakeries. Here in the US, the cookies are growing in popularity, but are still not that common. You’ll have to look in your area for a restaurant or bakery that specializes in French pastries to find some, and it might take even more time to find very good ones. You can also make them at home with just a few simple ingredients, where you can experiment with different flavors and fillings to customize your creations.
