Step 1: Prepare the Green Paste. In a small blender or mortar, crush the dry coconut, ginger, garlic, green chilli, and coriander leaves into a coarse paste.
Step 2: Tempering. Heat oil in a pressure cooker over medium heat. Add the mustard seeds, cumin seeds, curry leaves, and a pinch of asafoetida (hing).
Step 3: Sauté the Onions. Add the finely chopped onion to the cooker and sauté until it turns light golden brown.
Step 4: Cook the Paste and Tomatoes. Stir in your prepared green paste and sauté well. Next, add the chopped tomatoes and a little salt. Cook on low heat for about a minute until the tomatoes soften.
Step 5: Add Dry Spices. Lower the heat completely and add your cumin-coriander powder, turmeric, and onion-garlic masala. Mix the spices well.
Step 6: Add Black-Eyed Peas. Toss the washed fresh black-eyed peas into the cooker. Sauté them gently with the spices for one minute on low heat.
Step 7: Add Water. Pour in the warm or hot water to form a thick, semi-liquid (lapthapi) consistency. Mix everything thoroughly.
Step 8: Pressure Cook. Close the pressure cooker lid. Keep the gas on low and cook for exactly 2 whistles. Let the cooker cool down completely before opening the lid. Serve hot and enjoy!
