Thinly slice the oranges, then gently trim and shape the slices into flower shapes that fit inside your jumbo ice cube moulds.
Place one orange flower into each mould, pressing it lightly against the sides so it stays in place.
Add one cinnamon stick, one star anise, and one small sprig of rosemary to each mould.
Slowly pour water or squash into the moulds, filling to the top.
Freeze overnight, or until completely solid.
Remove from the moulds and add to festive drinks, cocktails, mocktails, or sparkling water.
