Step 1

Keep your watermelon chilled in the fridge and when you’re ready to make this smoothie, chop the watermelon into cubes and add to the blender jug.

Step 2

Squeeze the limes and add the juice to the blender jug.

Step 3

Blend well and then strain it through a kitchen sieve to remove the rough seeds so that you’re left with a very smooth drink. If you happen to use seedless watermelon you should still strain it so that your smoothie is perfectly smooth.

Step 4

Serve immediately.
