Santa’s spritz punch

Method

1. Take a cake tin or bowl that’s slightly smaller than the diameter of your punch bowl and put a small heatproof glass in the centre. Tastefully arrange the sliced orange, pomegranate seeds, cinnamon sticks and rosemary sprigs in the ring, then pour in enough boiling water to cover (see Know-how). Leave to cool, then put in the freezer.
2. Once frozen solid, run the frozen tin/bowl under warm water until the ice detaches, then carefully lower into the punch bowl. Pour over the prosecco, Aperol, cranberry juice and soda water in the quantities listed (or more/less but to the same ratio, depending on the size of your bowl).
