Add 2 tbsp of mustard oil to the wok and heat it up. Put in the bay leaf and cumin seeds, then sauté everything. A delightful aroma of whole spices will emerge.
Introduce the chopped onions and stir until they turn a light brown color.
Once the onions are lightly fried, add the grated ginger and garlic. Stir until the raw smell dissipates.
Incorporate turmeric powder, red chili powder, cumin powder, and coriander powder. Add a small amount of water and cook the spices while stirring well.
When the spices have released all their oil through stirring, introduce the chopped ash gourds. Thoroughly mix all the ingredients.
Now add 1 tbsp of salt and stir it in. Cover and let it cook on low heat for 2 to 3 minutes.(Pro tip: Adjust the salt according to your preferences.) After 2 to 3 minutes, uncover the lid. You’ll notice that the ash gourds have released moisture; this moisture helps in the cooking process. Cover it again.
Open the cover after a few minutes; the water should have dried up, and the ash gourds should be almost cooked. Now add ½ cup of water. Introduce the green chilis and cover it once more.(Pro tip: Adjust the water quantity based on your desired gravy consistency.) After a few minutes, the dish will be perfectly cooked. Finally, sprinkle fresh coriander leaves and turn off the flame.
Transfer the Ash Gourd Curry to a bowl and enjoy with steamed white rice, and Indian bread like plain or stuffed parathas, naan, chapati or roti.
