Baked Alaska

The name may be odd, but Baked Alaska is an elegant dessert. The core of this version is a "sandwich" of vanilla ice cream and blackcurrant sorbet between 2 layers of sponge soaked in rum-flavoured syrup.
This is then covered in a layer of meringue and put in a very hot oven for just a few minutes to brown the outside.

The magical and delicious effect comes from the contrast between the hot meringue and the cold ice cream and cake inside.
It is a little tricky to get right, but the main elements can be prepared several days in advance.
