One of my favourite French desserts is a Charlotte, and I had a tin of pears which needed using and a recipe from a French neighbour for making a chocolate and pear one. It doesn't need cooking, just chilling.
I bought a Charlotte mould when living there, but you can use any deep cake tin.
It's simple to make and delicious.
Charlottes can also be made with bread.

You need:

a large packet of boudoir biscuits [sponge fingers] or make your own 
200ml cream
a sachet of vanilla sugar [about 1 tbspn]
large tin of pears in syrup
