Cooking
Place the toovar dal and coriander seeds into a medium bowl, cover with 1 cup (240 ml) of boiling water, and let soak for 1 hour.
Pour the soaked dal, seeds, and their soaking liquid into a blender along with the julienned ginger. Process until the mixture is completely smooth.
Transfer the blended mixture to a saucepan, add 2 cups (480 ml) of water, and boil over moderate heat for about 15 minutes, or until the liquid reduces to 1. 5 cups (1200 ml).
Strain through a fine-mesh sieve and discard the solids.
Heat the ghee or sesame oil in a large saucepan over moderately high heat.
Add the caraway, cumin, and mustard seeds, frying until the mustard seeds sputter and turn gray.
Toss in the curry leaves for 5 seconds, followed immediately by the shredded cabbage and sliced carrots.
Stir-fry over moderate heat until the cabbage is wilted and soft.
Add the strained dal broth, the remaining 4 cups (960 ml) of water, and half of the chopped herbs to the pan.
Cover and simmer for 20 minutes or until the vegetables are tender.
Just before serving, stir in the lemon juice, jaggery or syrup, salt, and a generous dusting of black pepper.
Ladle the hot shorba into bowls and garnish with the remaining fresh coriander or parsley.
Don't Rush the Reduction: Boiling the blended dal and coriander mixture until it reduces is vital. This concentrates the coriander essence and creates the distinct soul of the broth.
