Make a biscuit base by crushing 8 digestive biscuits with a little melted butter.
Stew 1 kilo of rhubarb with 1 mixer can of ginger ale/beer (5 fluid oz I think). Once stewed, add a whole raspberry jelly mix and stir in. Once cooled, pour it onto the biscuit base and leave to set.
Strangely it doesnt taste of ginger or rhubarb much really, but it is gorgeous.
