Wash the gooseberry/amla well in water. Chop them and remove the stones/seeds inside. (I just cut them along the wedges. )
Take the chopped amla, curry leaves, chili, mint leaves together in a mixer. Grind well to a paste. If needed add 2-3 tbsp of water and grind well.
Take the ground paste along with yogurt, water, and salt. Blend well using a hand blender until nice and frothy.
Pour in glass and serve instantly.
