Soak the motor dal overnight or for 8 hours, so that it plumps up
Transfer this to a pressure cooker, add a tsp of salt and the turmeric. Cook until the dal/peas soften
Heat the oil until it smokes, then lower the flame and add the whole spices. Once they become fragrant add the sliced onions
When onions turn light brown, add the chilis along with the ginger and garlic pastes. Fry until their raw smell goes off
Add the potatoes and stir fry for 5-6 minutes. Next add all the spice powders and sugar along with the salt and 3-4 tbsp of water
Cook for 2-3 minutes and then add the tomatoes and wait until they soften
Next pour in the cooked motor dal (dried yellow peas), tamarind paste and give it a good mix. Then add ¾ cups of water and simmer on medium heat for another 10-15 minutes. Check for salt, adjust if needed
Turn the flame off and add the bhaja moshla. Let it sit covered for 5-7 minutes
Serve your ghugni (dried yellow peas curry), hot with some chopped chilis, onions and coriander leaves, along with piping hot chai
Extra tip: You can also serve the ghugni with some muri (puffed rice) and/or parathas/pooris (fried flatbreads)
