Tarka Dal
Rinse lentils. Bring water to a boil and add lentils.
Immediately add tumeric and coriander. Stir, turn heat to low,
and simmer for 18-20 minutes uncovered.
Over medium heat, melt butter. Add cumin and cardamom.
Stir briefly, then add onion and garlic.
Fry until onion starts to brown, about 6 minutes.
Add chili powder and boiled lentils (do not drain much).
Keep frying for another few minutes so lentils absorb flavors.
Sprinkle garam masala and stir. Serve.
