In a blender add in chopped Water Melon pieces preferably seedless along with sugar if required .Blend it into a fine puree without adding water. Now take the Popsicle mould.
Fill the popsicles mould till half .close it with the lid and the freeze it for about 2 hours till the water Melon Layer is set .After 2 hours before taking the popsicles mould out of the fridge add in the chopped mango pieces into a blender and sugar if required. Blend it into a fine puree without adding water.
Take the popsicle mould from fridge by this time the Water Melon layer would have set .Fill the mould with the Mango puree so the mould it filled now. Close it with a lid and freeze it for 6 hours or overnight .While unmoulding the Popsicle from mould show the mould in running tap water. Healthy Popsicle's are now ready .Serve it immediately.
If the Water Melon and Mango are sweeter no need to add Sugar.
I used Banganapalli Mango Variety.
De-seed the sugar from Water Melon before blending
If you dont have a popsicle mould you can also use a disposable plastic cup or even ice tray in fridges .If using the above cove it with a silver foil and insert a ice cream stick or tooth pick.
