Wash the mulberries well. Then smash it in a jug with a spatula or using hand blender.

Then add sugar, salt and water. Stir well to get them dissolved in the water. You can give it a blend in a juicer and filter it or give it a sieve to get the juice in another jug.

At last, keep the juice in a cold temperature, for a min or two in the refrigerator and serve it chilled.
