Potato Chutney

Something I made up using my mother's basic chutney recipe. Tasted so good it all got polished off in one sitting.

Heat oil in a kadhai, fry 1 green chilli, 1 inch piece of ginger chopped fine and 1 tbsp channa dal for 2-3 minutes.
Peel two boiled potatoes, add to the mixture and stir a couple of times.
Add kokum paste, take off the flame and let it cool.
Blend it all in the mixture.
Pour into a mixer, add salt to taste, and grind till all the potatoes are are pureed and the dals are coarsely ground.
Temper with mustard seeds and curry leaves.
Tastes best when cold.
