Brasillé is a traditional pastry made with flaky, buttery puff pastry, lightly salted butter, sugar, and eggs. Puff pastry is rolled out and buttered, then shaped into its characteristic oval shape before it is brushed with beaten eggs, sprinkled with sugar, and baked until puffed and golden on top.
This French specialty used to be prepared out of simple bread dough and lard, but it was later re-invented by a French baker called Emilie Roussel, who replaced lard with butter and added sugar to the combination. Brasillé earned its name from the French word brasier, meaning a pan of hot coals or embers, referring to the method of baking the pastry in an oven of hot coals that gave the original pastry a slightly burnt top.
