Ingredients:

about half a fresh water melon, cut into chunks
juice of 1 sweet lime (musambi)
juice of half a lemon
1 tbsp honey
1 1/2 tsp fresh ginger juice
3/4 tsp salt
1 tsp chaat masala (optional)


OR

about half a fresh water melon, cut into chunks
2 tomatoes, deseeded and chopped
1 cup orange juice
1 tbsp honey
1 tsp rose syrup
freshly crushed pepper
5 to 6 torn mint leaves
3/4 tsp salt


Method:

If you chill the watermelon chunks and then blend them, you can serve this cooler almost immediately, when the flavours are very fresh which would be the best way to serve this.
Whatever your set of accompanying ingredients, put them along with the water melon chunks and blend till a smooth homogenous mixture is obtained.
If you do not like the grainy texture of mixture, strain and serve. Do add sugar if you feel your watermelon isn't sweet enough.
You can serve this in a glass as a drink or in a bowls as a chilled fruit soup. If you freeze this mixture, you can serve it as granita.

If you prefer ice in your cold drinks, adding ice to these watermelon coolers only dilutes them and makes them taste awful. Here are two suggestions to overcome this:
 - You can pour out a couple of glasses of the watermelon concoction into ice trays and freeze them for use in these, instead of ice.
 - You can also chill the watermelon cooler in the freezer for about halfan hour to an hour till the top layer just freezes. Break this layer, mix and serve this slush-like mixture.

This recipe makes enough for 3 to 4 tall glasses.
