Prepared with commercial puff pastry, this first recipe is the perfect primer. Nicolas used rolled sheets, which he cut into squares. The next steps were relatively simple: He topped each square with pastry cream, almond powder and apricot halves. Then he connected the two ends, brushed on an egg wash and popped the tarts into a hot oven. All that was left was to wait for the scent of golden pastry to fill the air.
