Mix the pointed gourds with salt and turmeric powder. Keep aside for 10 minutes. (Pro tip: You may prick each piece lightly with a fork first. It helps the masala seep in nicely later.)
Fire up the chullah (clay stove) but you can cook it on a gas stove as well.
Place a kadai on the clay stove.
Pour oil into the wok (kadai). Fry the pointed gourds from all sides until they turn golden brown. Take them out on a plate.
Add cinnamon sticks, cardamom, and cloves to the oil. Stir them until they release their flavors.
Add onion-ginger-garlic paste and sauté it well.
Add turmeric powder, red chili powder, coriander powder, and cumin powder. Stir well.
Add a little bit of water to make a thick paste.
Add ½ tsp of salt and continue stirring. Add water if required. After the spices release oil, add the fried pointed gourds to the paste. Mix well for 5 minutes.
Add enough water according to your gravy requirement and curd-cashew paste and stir well. Add green chilies, salt to taste, and sugar.
After 5 minutes Doi Potol is ready and pour it into a bowl. Serve it with steamed rice, jeera rice, pulao. You can also pair the dish with Indian bread like roti or paratha or deep-fried puffed bread called Luchi.
