Ingredients
Unbleached all-purpose flour, for dusting
1 sheet (about 14 ounces) all-butter puff pastry, thawed
2 tablespoons Dijon mustard
1/2 pound Gouda, rind removed, cut into 24 approximately 3/4-inch cubes
Lingonberry jam and freshly ground black pepper, for serving
Preparation
Preheat oven to 425°F. On a lightly floured surface, roll out pastry to an approximately 11-by-16-inch rectangle. Trim edges straight to a 10-by-15-inch rectangle. With the tines of a fork, prick pastry all over at 1/2-inch intervals. Cut into twenty-four 2 1/2-inch squares (a 4-by-6 grid). Press each square into the cup of a mini muffin tin. Spoon 1/4 teaspoon Dijon into bottom of each pastry shell. Refrigerate until pastry is firm, at least 15 minutes.
Bake until pastry cups are puffed, golden along edges, and beginning to set, about 15 minutes. Working quickly, remove from oven and press a cube of cheese into center of each pastry with the handle of a wooden spoon. (Cheese should depress pastry to reach bottom of cup.)
Continue baking until pastry is golden brown and cheese is melted, 8 to 10 minutes more. Let cool in tins a few minutes. Transfer to a serving tray, top with jam, and sprinkle with pepper. Serve warm.
