- 4 cups moong beans
- 2 tablespoons vegetable oil
- 1 1/2 teaspoons cumin seeds
- 1 onion, diced
- 1 (2 inch) piece fresh ginger, peeled and grated
- 4 cloves garlic, minced – or more to taste
- 2 teaspoons curry powder
- 1 teaspoon ground turmeric
- 1 teaspoon paprika
- salt to taste
- 2 tomatoes, chopped
- 1 jalapeno pepper, chopped
- water to cover
- 1 sprig fresh curry leaves
- 1 lime, juiced
- Put moong beans in a large container and pour enough cold water over the beans to cover by several inches; soak 8 hours to overnight.
- Drain and rinse beans; set aside.
- Heat oil in a pressure cooker over medium-high heat until smoking. Cook cumin seeds in the hot oil until they sizzle, about 90 seconds. Add onion to the pot; cook and stir until they begin to turn translucent, 2 to 5 minutes. Add ginger, garlic, curry powder, turmeric, paprika, and salt into the onion; cook until fragrant, about 1 minute more.
- Stir tomatoes and jalapeno pepper into the onion mixture; cook and stir until the tomatoes soften, about 5 minutes. Add moong beans to the mixture. Pour enough water into the pot to cover the ingredients by at least 2 to 3 inches; add curry leaves and lime juice.
- Lock the lid onto the pressure cooker, bring the cooker up to pressure, and reduce heat to keep the pressure steady. Cook 15 to 20 minutes.
- Remove the cooker from the heat, place in the sink, and run cold water over the lid of the cooker until the pressure has been released. Carefully remove the lid.
