1 (17.5 Ounce) Package Frozen Puff Pastry, Thawed
6 Red Apples, Thinly Sliced
½ Cup Lemonade
12 Pats Unsalted Butter
½ Cup Superfine Sugar
½ Cup Apricot Preserves
1 Pinch Coarse Sugar Crystals, Or As Needed
Step 1 Preheat oven to 350 degrees F (175 degrees C).
Step 2 Cut puff pastry into 12 equally-sized squares and arrange on a baking sheet.
Step 3 Dip apple slices in lemonade and place diagonally onto each puff pastry square; top each with 1 pat butter. Sprinkle superfine sugar over each square.
Step 4 Bake in the preheated oven until tartlet edges are golden, about 12 minutes.
Step 5 Bring apricot jam to boil a saucepan; cook and stir until jam is thinned, 1 to 2 minutes. Brush jam onto warm tartlets; sprinkle each with sugar crystals.
Note: I quartered and cored my apples and cut with a mandolin.
