Directions:
1. Thaw the puff pastry if you haven't done so yet. It should take about 20-30 minutes.
2. Prepare a bowl with some water and the lemon juice. Cut the apples in half, remove the core and cut the apples in paper thin slices, as shown in my picture. Leave the peel so it will give the red color to your roses. Right away, place the sliced apples in the bowl with lemon and water, so that they won't change color.
