The method of preserving watermelons that we want to share here was first developed in India. It involves covering the watermelon in a layer of paraffin oil or wax that protects it from the external environment and also prevents it from losing its moisture. The protective layer is created in the following way:
Wipe the watermelon with a dry cloth (you don’t need to wash it).
Melt the paraffin oil or wax using a water bath. If you can’t find either of these things at the store, you can use cheap candles. Remember to remove the wick and break the candles into small pieces.
Allow the substance to cool slightly, then apply it evenly to the surface of the watermelon, turning the melon over until the whole of it is covered in a layer about 0.5 cm thick.
Allow the paraffin oil/wax to cool down and harden.
