1. The watermelon has been weighed after being cleaned. You may need to purchase approx 1 kilo watermelon and clean & cut into chunks before measuring/weighing it.
2. If you don't wish to use ice cubes, ensure that the watermelon & cucumber are adequately chilled.
3. The addition of lime juice gives the drink a lift, however it won't taste very good at room temperature, so make sure you serve this drink chilled - with or without ice.
