Here's the recipe.
Toordaal - 1/2 cup (yes, i measured it this time! :-))
Cumin seeds - 2 spoons
Red chillies - 4 (Adj. a/c to your spice level!)
Tamarind - Lemon sized
Turmeric powder - a pinch
Salt to taste
Mustard seeds, hing, curry leaves and cumin seeds for seasoning
Cilantro for garnishing (optional)
Wash and drain the toordaal. Add the cumin seeds and add some water and soak it for an hour.
Grind the daal, cumin seeds and redchillies with little water into thick paste.
In a pan, add tamarind extract to this paste and add some more water as this thickens pretty fast. Add turmeric powder and salt. Let it boil till the raw smell goes. Add more water if required. Season with mustard seeds, hing, curry leaves and jeera.
Tastes good with Rice and any curry. You can have it as soup also.
