It is very easy to cook. Take fresh aalu. Leave for a day. The next day, separate its leaves from its stem. Then peel the stems and cut the leaves and stem together. Soak some pulses like groundnut, chavali, chickpea (harbhara/chana), green peas whatever you like. Then boil chopped alu and soaked pulses together. Boil till the alu gets smooth and smashy. Keep it aside.

Heat a pot. Add some oil. Then add some crushed garlic petals to the oil (more garlic, better taste). Stir the garlic well until its leaves smell. Then add finely chopped onion, stir well. Then add finely chopped tomato to it. Add your (homemade or brought from the market) masala to it. (masala quantity-how spicy you want) finely add that boiled veggies to it. Add salt and water to make gravy. Let it boil.

Then take some crushed coconut, vertically chopped onion, garlic petals, ginger. Shallow fry this all together on low flame until it gets brown color. Off the gas let it cool. Then smooth blend it in a mixer. Add this mixture to the boiling veggies. Check the salt and masala, add those if you want more. Boil it again to make it thick.
