Finely grate the lime zest and place into a saucepan with 2 cups (500ml ) water, sugar and mint. Bring to the boil, reduce to a simmer and cook 2 minutes. Remove from the heat, and set aside until cold. Strain and discard solids.
Juice the limes, you'll need 1/2 cup (125ml) lime juice. Pour into blender, add chopped cucumber and lime/mint syrup. Blend on high until smooth. Strain mixture through a fine sieve and pour into ice block moulds.
Freeze for 2 hours before adding wooden ice block sticks and freezing for a further 4 hours or until frozen. Run moulds briefly under warm water to help release ice blocks.
