Step 1

Heat the oil in a skillet over medium heat. When the oil is hot, add the mustard, fennel, and fenugreek seeds, and the urad dal. Cook until the seeds start to sizzle and the urad dal changes color, about 30 seconds. Stir in the curry leaves and asafetida. Add the onion and garlic and cook until translucent, about 4 minutes.

Step 2

Add the tomato, sambhar powder, tamarind, and cayenne, and mix well. Cook until the tomatoes are saucy, 6 to 7 minutes.

Step 3

Add the edamame, coconut milk, water, and salt. Cover and cook until the edamame are tender, about 25 minutes. Taster and adjust salt, heat (cayenne), tang (add lemon juice if needed). For thinner curry, add more water and bring to a boil. Serve hot with Dosa crepes, idli rice cakes or over rice.

Step 4

Pressure Cooker/ Instant Pot: Follow steps 1 to 3 on saute mode. Add the edamame, coconut milk, water, and salt and cook for 6 to 8 minutes at high pressure. Natural release. Taste and adjust salt, tang and heat.
