Method: Soak imli or tamarind in lukewarm water for 1-2 hours or you can do this a day before. Then with your fingers mash them and throw the stones. If you are using stoned tamarind or imli just mash with your fingers. Now put crushed jaggery or sugar along with 1/2 teaspoon of salt and ginger powder. Roast
cumin seeds along with dry chillies in a dry frying pan. When the colour turns brown put them on a plate. Now crush them with a rolling pin or pestle and mortar. Sprinkle this on tamarind sauce. Taste it. If you like you can mix a few teaspoons of mint sauce in it or crushed mint leaves. Boil aloo and arwi and peel them. Dice them and keep aside. When you serve, put diced aloo and arwi in a small bowl for each
individual person. Sprinkle salt, chat masala, red chilli powder, a table spoon of beaten natural yogurt and tamarind sauce. This is tasty and very-very suitable for fast.
