I first had a macaron in Paris years ago, and have since enjoyed them every chance I get! Good thing they’re modest in size, although that isn’t helpful when I consume two, four or more at a time… Anyway, they are pretty easy to find over here. Every patisserie makes gourmet versions and groceries carry more basic ones.
Macarons are meringue-based, made with egg whites, icing sugar, granulated sugar and ground almonds. The filling is usually ganache or buttercream or less satisfying (in my opinion) jam. Traditional flavors are chocolate, pistachio and raspberry, but newer flavors like green tea, black forest and praline have become very popular.
It is generally believed that the macaron was created in the 18th century in a French convent.
