finely crush the biscuits in a food processor for 30 seconds, or put them in a plastic bag and roll with a rolling pin. Transfer to a bowl and add the melted butter. Stir until all the crumbs are moistened, then pour the mixture into a 20cm springform tin and press firmly into the base (if you are adding chocolate to the mixture you will also need to put the biscuit mixture up the side of the tin). Refrigerate for 20 minutes, or until firm.|
Variations - base
chocolate ripple biscuits
butternut cookies + 1 tsp mixed spice
