Pressure-cook the toor dal with turmeric and 3 cups water until soft, then mash well.
Simmer the drumstick, shallots, tamarind pulp, salt and 2 cups water for 10 minutes.
Add the mashed dal and sambar powder, and simmer 10 minutes until slightly thick.
Heat the sesame oil, pop the mustard seeds, and pour over the sambar.
