Peal and chop the apples and add the lemon juice so they don't get dark. Melt the butter with the cinnamon sticks in a pan and add the apples.

Once they get brown, add the sugar and cook until caramelized

Cut the puff pastry into small circles using a glass (I cut 11 pieces)

Fill each piece with a spoon of the caramelized apples. Seal them well using a fork.

Paint the with the remaining sauce and bake following the puff pastry package instructions.
