• Cover a large, flat baking tray with foil.
  • Place small scoops of vanilla ice-cream on the tray and freeze until hard.
  • Melt chocolates in separate bowls over pans of simmering water.
  • Once melted, set aside to cool.
  • Transfer ice-cream scoops to a wire rack over a baking tray and spoon the dark chocolate over each scoop; it should harden immediately.
