Mussels in Light Tomato Broth

Ingredients
Method
In a 4-quart pot over medium heat, add the oil. Add the ginger, garlic, cumin, black peppercorns, asafoetida, and salt. Cook, stirring constantly, for 1 minute. Add the tomatoes and cilantro and cook for 5 minutes, stirring occasionally. Add 2 cups of water and cook for 8 minutes on a low heat. Add the mussels, cover and cook for 5 to 6 minutes, or until the mussels are opened. Remove from the heat. Transfer the mussels and broth to a serving bowl and finish with the tempered oil.
In a small pan over medium heat, add oil. Add the curry leaves and mustard seeds; when the mustard seeds begin to pop, remove the oil from the flame, about 30 seconds. Drizzle the oil over the mussels and broth.
