Frugal and scrumptious!
Some were rolled in cocao, some in chopped walnuts, into some a walnut piece was embedded, and others we left plain. That made four varieties. If we'd had any coconut flakes, chocolate sprinkles and glace cherries around there could have been three more.
For a greater variety a sultana, nut or ball of marzipan can be hidden in the centre of some.
