Simply fill your ice cube tray with the cranberries, chopped orange, and rosemary sprigs.
Then, carefully pour the pomegranate juice over the top.
Cover the tray and pop it in the freezer overnight.
When you're ready to enjoy your drinks, just add 3-4 of these festive cubes to a glass and pour over some bubbly Prosecco!
Cheers to holiday happiness!
