This flavorful south Indian stew features lentils cooked with meltingly tender cubes of ash gourd or white pumpkin. Serve with rice or dosa for a nourishing meal.
Heat 1 teaspoon oil in a saucepan or pot over medium high heat. Add to it the mustard seeds, cumin seeds and asafetida. As soon as you hear the mustard seeds begin to pop, add the curry leaves and mix.
Add the pumpkin cubes and a cup of water. Bring to a boil, then cover the pan and cook 8-10 minutes or until the pumpkin is tender.
Stir in the tomatoes and tamarind. Let the tomatoes cook until pulpy, 2-3 minutes.
Add dal to the pan and mix in.
Stir in the sambar powder and jaggery. Return to a boil and let the sambar simmer for another two to three minutes. Add salt to taste and turn off heat.
Optional tadka for finish
Heat the remaining 1 tablespoon oil and add the mustard seeds and curry leaves. When the mustard crackles, pour the oil over the dal and mix well.
