Combine mango cubes with jaggery and salt in a sauce pan. Bring the mixture to a boil, then lower the heat and simmer until mango is very tender and jaggery is completely melted, about 20-25 minutes.
Then using an immersion blender or regular blender, blend the mixture to a smooth pulpy consistency.
If the pulp looks too stringy, strain it through a sieve. Mine was pretty smooth, so I didn't strain the pulp.
Mix 2-3tbsp of the pulp with cool water for a refreshing Aam Panha. Enjoy!!
