Start by soaking the mash ki dal in water for about 1-2 hours. Drain the excess water after the dal has been soaked.

In a medium sized pot, add the oil, and saute the onions until golden brown. Now add the tomatoes and fry for 1-2 minutes on high flame.

Add the spices, and cook this masala for about 10 minutes on high flame while stirring constantly.

Once the tomatoes have cooked through, and you can see the oil separating from the curry, add the mash ki dal

Add about 1 cup of water and cook on medium low flame. You will need to keep adding water little by little until the dal cooks through.

Garnish with chopped coriander, ginger and green chilli.
