Wash the gooseberry/amla well in water. Chop them, removing the stone/seed inside. I just cut them along the wedges.
Take the chopped amla, curry leaves, chili, mintleaves together in a mixer. Grind well to a paste. If needed add 2-3 tablespoon ofwater and grind well.
Take the ground paste along with yogurt, water, and salt. Blend well using a hand blender until nice and frothy.
Pour them in glasses and serve. This can also be refrigerated and served later. If serving after refrigeration, mix well and serve.
