Take the pulp out of the mangoes and blend in a blender with sugar to taste and a little bit of salt.
Now take a plastic sheet and spread the pulp on to it.
Keep this on a chatai (mat) and dry it out in the sun.
When the top is dried, turn and dry some more till no moisture is left.
Your aam papad is ready.
You can do the same if you want a spicy one, by adding kala namak (rock salt) and spices to your liking.
