Mojito Ice Cubes with a Color-Changing Twist

Method

1. In a medium pot, bring the water and the shredded red cabbage to a boil. Once boiling, strain the cabbage through a sieve set over a bowl, collecting the blue liquid.
2. Pour the blue liquid into an ice cube tray. You should have about 1 cup (235 ml) of blue water. Reserve the remaining blue water (about 2 cups) for later, and freeze the tray for 6 hours or overnight.
3. In a separate pot, combine the reserved blue water with the sugar and bring to a boil, stirring until the sugar dissolves completely. Remove from heat and let cool.
4. In a bowl, mix the lime juice with the remaining 1½ cups of water. Pour this mixture into another ice cube tray and freeze for 6 hours or overnight.
5. Once frozen, remove the blue ice cubes from the tray and blend them in a blender until finely crushed. Divide the crushed blue ice among 4 glasses.
6. Rinse the blender thoroughly to remove any blue residue.
7. Add the lime ice cubes and 8 of the mint leaves to the blender. Blend until finely crushed. Spoon this mixture on top of the blue ice in each glass.
8. Slowly pour the white rum and the cooled blue syrup over the ice. Garnish each glass with a sprig of fresh mint. Serve immediately and enjoy the color change!
