Yes it really does serve ten, it is so rich! If you do not have a spring-form tin, spoon the mixture into a freezer-safe shallow dish, cover with cling film, then freeze. You can make half the quantity if you prefer, or simply cut off and thaw the amount you wish to serve and leave the rest in the freezer.
Equipment and preparation: you will need a 20cm/8in loose-bottomed or spring-form tin.
