First of all you need to make the caramel to go on the inside. Put the water and sugar in a pan, preferably a really old one as it is a pain in the ass to clean!!! Heat on a medium temperature until it starts simmering.

Keep on heating for a fairly long time in till it starts thickening and stars to turn a brown colour.

If you have a thermometer put that in it and wait in till it reaches about 350 degrees. Its not mould in the caramel just sugar. Honestly!!!
