The English word macaron is derived from the French macaron, which comes from the Italian maccherone, or "fine dough." The macaron's origin isn't clear, but Catherine di Medici may have brought it to France from Italy as early as 1533. It wasn't until the 1900s that Pierre Desfontaines of Parisian pastry shop and café Ladurée decided to take two cookies and fill them with ganache.
