Pani Lau aru Butor Dali
A humble, comforting Assamese dal where delicate bottle gourd (pani lau) melts into split pigeon peas (butor dali), creating a light, soupy lentil dish that's subtly flavored with ginger and tempered with mustard oil. This everyday staple from Assam is gently simmered, letting the natural sweetness of the gourd balance the earthy lentils without overwhelming spices.
For 4 servings
- prep
Wash the dal and prep the gourd.
Rinse the toor dal in 2-3 changes of water until water runs clear. Peel the bottle gourd, discard the spongy core if any, and cut into small even cubes.
- pressure cook · ~20 min
Pressure cook the dal and gourd.
1.Add dal, bottle gourd cubes, grated ginger, turmeric powder, and 3 cups water to the pressure cooker.2.Close the lid and cook on medium-high heat until the first whistle.3.Lower the heat and cook for 2 more whistles, then let the pressure release naturally. - prep
Mash the dal lightly.
Once the pressure drops and the lid is safe to open, use a wire whisk or ladle to lightly mash the dal and gourd together into a uniform, soupy consistency. Stir in the salt.
TIPDon't over-mash. The texture should be light with some visible soft lentil grains and tender gourd pieces. - boil · ~5 min
Simmer the dal to the right consistency.
Place the cooker or transfer the dal to a deep pan and bring to a gentle boil over medium heat. Add a little more water if it's too thick — this dal is meant to be thin and soupy. Simmer for 5 minutes.
TIPThe consistency should be on the thinner side, like a light broth with soft lentils and gourd. - temper · ~3 min
Make the mustard oil tempering.
1.Heat mustard oil in a small pan over medium-high heat until it reaches its smoking point and the raw smell disappears.2.Lower the heat and add the crushed garlic cloves.3.Sauté until the garlic turns light golden and fragrant, about 30 seconds.TIPMustard oil must be heated to smoking point to mellow its pungency. Don't skip this step or the dal will taste harsh. - mix · ~2 min
Pour the tempering over the dal.
Immediately pour the sizzling garlic-mustard oil over the simmering dal. It will sizzle dramatically on impact. Cover the pot for 2 minutes to let the smoky aroma of mustard oil and garlic infuse the dal.
- garnish
Garnish and serve hot.
Sprinkle fresh chopped coriander leaves on top. Ladle into bowls and serve immediately with steamed white rice.
What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Use mature bottle gourd with firm skin and no seeds for a clean, sweet flavor.
- 2Peel the bottle gourd thickly to remove the fibrous layer just under the skin.
- 3Do not cut the gourd into chunks larger than 1 cm so they cook evenly with the dal.
- 4Let the pressure release naturally to allow the dal and gourd to fuse into a silky texture.
- 5For a thinner consistency, add hot water after mashing rather than cold to avoid shocking the dal.
- 6Smoke the mustard oil until it is visibly hazy and a wisp of white smoke rises to remove its pungent edge.
- 7Cover the dal immediately after pouring hot tempering to trap the smoky aroma.
