Kouign-Amann (Caramelized Butter Sugar Pastry)
With only five ingredients in this Breton pastry (flour, butter, sugar, yeast, and salt), the folding technique decides almost everything. Butter is wrapped in the dough and sugar is scattered over each fold, three times in all. In a hot oven the sugar melts into a glassy, dark caramel shell while the layers inside stay moist with butter.
