Celebrate late summer with this Easy Tarte Tatin with Plum and Basil, a dessert that's made with puff pastry and is easier than pie (pinky promise!)
Melt the butter in a heavy ovenproof 9-inch-diameter skillet over medium heat. Sprinkle remaining 2/3 cup sugar evenly over melted butter. Place basil sprig in the center of skillet. Tightly arrange plums, cut side up, in concentric circles over the basil in skillet. Cook over medium heat until syrup turns deep red, pressing plums slightly to form a compact layer, about 20-30 minutes depending on the firmness of the plums. Shake the pan slightly every now and then to prevent sticking Remove skillet from heat and cool for 10 minutes.
If the tarte appears to stick to the skillet, rewarm over high heat to loosen, about 3 minutes. Place a large platter over skillet. Using oven mitts, hold skillet and platter together and invert, allowing the tart to settle onto the platter. Slowly lift off skillet. Discard basil sprig and garnish with fresh basil leaves before serving.
