The taste is much like cucumber or zucchini.
Here's my recipe for natural viagra in your diet (The sad thing is Niket is allergic to watermelon :( )
rind of 1 watermelon, thick green skin peeled and cubed
(you can remove the red part too, i just let it be)
ginger garlic paste
sesame seeds for tempering (I think nigella would be good too)
oil for cooking
salt to taste
1 tsp each of turmeric, coriander and all spice for seasoning
Heat oil, add tempering. Let it splutter. Add onions and cook till done. Add cubed rind, salt and powdered spices and cook covered. Check for doneness. It should be done in 15 mins.
Serve hot with rice or chapatis.
