1/2 cup skinned hazelnuts
1/4 cup granulated sugar
Two 8-by-10-inch sheets puff pastry (or 1 box), thawed in the fridge
All-purpose flour, for dusting
1 egg mixed with 1 tablespoon water or milk, to make an egg wash
1/4 cup grated semisweet chocolate (grated on a small-holed grater)
Mix it up! Use sweet or savory fillings. For a savory idea, try grated Parmigiano-Reggiano plus chopped thyme or oregano, or Asiago cheese with a pinch of cayenne--so good!!
