Ragda Boda Saaru ( Olden days the masala for any curries was manually ground , the washed water of the manual grinder is used here to prepare the rasam )
Retain the washed water of the ground masala ( Sukke /Sagle ) n also a little masala of the same . Add water for rasam consistency , salt n boil well . season with a tsp of oil, 1/2 tsp of mustard seeds n curry leaves .
This is Amchi specialty almost forgotten now .
