Prepare the apple slices and put them into a large bowl of cold water with the squeezed lemon
Microwave the apples for 3 to 5 minutes until soft enough to bend slightly but not cook them.
Preheat the oven to 180ºc
Roll out the puff pastry. Divide into 8 sections by cutting the rol into quarters then halving each quarter. You will end up with 8 approximately 6 cm strips
Dust the pastry strip with ground cinnamon
Spread the salted caramel over the strips with the back of a spoon or butter knife
Lay the apple slices along the top of the pastry strip, overlapping them. The skin side of the half moon poking over the top of the pastry strip and the straight side in the pastry
Sprinkle the apple/pastry strips with extra sea salt
Fold the bottom half of the pastry strip over the top half, leaving the half moons of apple sticking out the top.
Roll up the folded pastry strips until they look like a rose made of apple at the top
Place 'rose' side up, in a cupcake tin
Repeat until all are done and bake for 20 -30 minutes.
Using a tea strainer or small sieve, sprinkle with icing sugar.
