Prepare a bowl with the lemon juice and a cup of water. Wash the red apples, then cut them in quarters and remove the cores. Slice thinly into the bowl of lemon water. Microwave the apples in the bowl about 3 minutes.
Sprinkle the flour onto a clean table top, then unroll the puff pastry on top of the flour. Roll the dough into a 12" x 9" rectangle. Cut into 6 strips, 2" x 9".
Mix the apricot preserves with 2 tbsp of water. Warm in the microwave until smooth. Spread onto the puff pastry dough in a thin layer.
Heat oven to 375°. Drain the apples and pat dry on paper towel.
Arrange the apple slices on the dough strips, with the red skin showing above one long edge. Fold up the bottom of the dough onto apple slices. Pick up one end of the strips and roll up. Place in muffin pan.
Place in heated oven and bake 45 minutes. After the first 25 minutes, place foil over the top to prevent too much browning. Turn the oven down to 325° to finish baking.
