This recipe makes two versions: a lighter, sorbet-style batch (500 ml coconut drinking milk) and a richer, creamier batch (300 ml coconut drinking milk plus 200 ml canned full-fat coconut milk). Leave a little headspace in the molds, as the liquid expands as it freezes. If your molds won't hold the sticks upright, freeze for about 1 hour until slushy, then insert the sticks. Store frozen for up to 2 weeks.
