To pastry chef Jean-Yves Charon, a kouign amann tastes like home. From his native Brittany, this classic Breton “butter cake” relies on layers of handmade puff pastry dough to create a decadent treat with a sweet, buttery center and crisp caramelized-sugar coating. Hand made with the finest natural ingredients, the frozen pastries are simple to prepare—just let them rise overnight and bake. They emerge from the oven with crunchy, sugar-speckled exteriors, tender interiors and an irresistible buttery aroma.
