Peel the apples and keep them in a bowl of cold water with a the juice of 1 lemon to keep them from discolouring. quarter and core apples

Chose the frying pan that can also go in your oven, and a plate that is a slightly larger to use as a template to cut the puff pastry once rolled out.

Roll out the pastry to about 4 mm thickness, cut a disc about 3 cm wider than the plate, keep this to one side while you now make the caramel.

To make sure your pan is super clean and free from grease, put it on a high heat and when hot pour in a glass of water and let that boil for 30 seconds or so before pouring away. Then add your sugar and on a medium heat tilt the pan while it gradually melts.

You can see in these images the sugar melting and caramelising, when all the sugar is caramel add the butter sliced and stir it into the caramel. The butter will help you turn out the tart when finished.

Turn off the heat and arrange apples clockwise, presentation side down and then the centre. I squeezed in a few more after the second image as they will naturally reduce in size when they cook so you really need to pack in all of the apples. Then turn the heat back on to medium and simmer for 8-10 minutes to start the cooking of the apples.

Cover with pastry then tuck the edges inside the pan but out side the apples, this keeps the pastry in place. Use something blunt like the end of a spoon, the pan is hot and you must be careful to keep your fingers out of the caramel, this is why chefs end up with asbestos fingers.

Prick a few holes in the pastry with a knife, then bake at 180c for about 30 minutes or until the pastry is fully cooked. Leave to cool for 20-30 minutes before turning out. Use a pallet knife to loosen the edge of the pan.

Time to turn the pan over, use the plate from earlier and place on top of pan, hold it firmly in place with one and and confidently turn it upside down. It's important to let the tart cool to slightly warm so that if caramel gets on you it will not burn, but if you let this go cold the caramel will set and stick to the pan, if it feels stuck place back over the stove for 30 seconds or so just to unset the caramel.

Moment of truth, carefully pull off the pan, if it is stuck turn it back over and give another 30 seconds over heat. You can enjoy the tart straight away or chill it and portion when cold and re-heat later on, serve with vanilla ice cream or whatever you feel like.
