A very popular treat in France, macarons have charmed foodies of other nations with their delicate texture and pretty colours. Macarons are not to be confused with the more familiar coconut macaroons that you're probably used to; instead, macarons are made with flavored meringue halves sandwiched around a rich filling. This recipe is for cocoa meringues with chocolate ganache filling, but you can customize it to any flavour and filling you'd like.
