Lay 1 packet of croissant triangles around a pizza stone with pointy ends out.
Lay the other packet opposite with pointy ends in. You might want to visit the site! (I'm not trying to sell anything but it's not my idea!)
Put the butter, sugar, apples (squirt lemon on the apples while you are preparing to stop them going brown), and spice in a microwavable bowl and cook on full power for 4 minutes.
Spoon the mixture evenly around the dough ring.
Take an outside piece of dough and wrap it over at an angle and tuck in on the inside. Next take an inside piece. Repeat.
Glaze with beaten egg and stick in the oven at 190 C or Gas 5 for about 25 minutes or until crisp and golden.
You could add a few chopped nuts to the top for extra crunch but be careful it doesn't burn.
