Chop a half watermelon into cubes. De-seed the cubes and then put it into the freezer for 2-3 hours.

Take out the watermelon cubes from the freezer. Put them in the mixer grinder along with milk and sugar.

Blend all the ingredients together untill the melon cubes are perfectly blended and the mixture becomes smooth.

Strain the mixture using a muslin cloth (optional). I did not strain it. The pulpy texture is nice-I liked it.

Pour the milk shake into a glass and garnish it with tiny watermelon cubes.

Serve the milk shake chilled.
