If using dried gundruk, rinse it thoroughly in cold water and soak it for about 20-30 minutes. Drain and squeeze out excess water.
If using fresh gundruk, wash and chop it roughly.
In a pan, heat ghee or oil over medium heat.
Add cumin seeds and mustard seeds. When they start to crackle, add chopped onions and sauté until they become golden brown.
Add minced garlic, ginger, and green chilies (if using). Cook for another minute.
Add chopped tomatoes, turmeric powder, ground coriander, and salt. Cook until the tomatoes are soft and the spices are well blended.
Add the prepared gundruk to the pan and stir well to combine with the spices.
Cook on medium heat for about 10-15 minutes, stirring occasionally. The gundruk should become tender and take on the flavors of the spices.
Sprinkle garam masala over the dish and mix well.
Adjust seasoning with salt if needed.
Garnish with chopped fresh coriander leaves.
Enjoy your meal!
