Who could've predicted that the omission of one "o" could cause so many problems? Pronounce "macaron" like a French person to a non-French person and you'll have to repeat yourself, perhaps multiple times, until the back of your throat aches from forming one too many rolled Rs. The English word macaroon is derived from the French macaron, which in turn comes from the Italian maccherone, or "fine dough." ("Macaroni" is also derived from the word maccherone.)
The macaron's origin isn't clear, but it may have been brought to France from Italy as early as 1533 by Catherine di Medici and her pastry chefs. Macarons gained fame in 1792 when two Carmelite nuns seeking asylum in Nancy during the French Revolution baked and sold macarons in order to support themselves, thus becoming known as"the macaron sisters." The macarons they made were a simple combination of ground almonds, egg whites, and sugar. No special flavors. No filling. Just 100% cookie
It wasn't until the 1900s that Pierre Desfontaines of Parisian pastry shop and caféLadurée decided to take two cookies and fill them with ganache. Today Ladurée continues to be one of the first stops for macaron-crazed fans in Paris. No longer a humble almond cookie, the macaron turned into a versatilely flavored treat with a thin, light crust briefly giving way to a layer of moist almond meringue following by a center of silky smooth filling.
