Kholamba can be made with a variety of veggies - you can use only brinjals or just potaotes or even just drumsticks. I used all the veggies that i had as that is the only way I can make my husband eat his veggies :).
1 cup tur dal (split pigeon peas)
1/2 teaspoon tamarind pulp (I have a bottle of tamarind concentrate that I use)
salt to taste
1 tablespoon oil
1/2 teaspoon mustard seeds
5 curry leaves
2 whole red dried chillies
2 to 3 teaspoons kholamba powder
1 cup dices ash gourd
1 baby brinjal/eggplant
7 to 8 french beans
Wash and cook the dal with 3 cups of water in a pressure cooker upto 3 whistles. Cut all the veggies into bite size pieces and cook them with enough water untill soft - Add the carrots, potato and ash gourd first and after 10 minutes add the other vegetables and a pinch of salt and let it all get cooked well.
Once the dal is cooked - just mash it with the bottom of a ladle/spoon. To this add the kholamba powder and tamarind pulp.
In a karahi add the oil. When it gets hot add the mustard seeds. when they splutter add the curry leaves and the whole dried red chillies. To this add the dal and the cooked vegetables. Mix well and add salt to taste. Bring it to a boil and then lower the heat and let it simmer covered for about 15 minutes. add chopped cilantro for garnish ans serve with rice.
