What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Rinse the masoor dal thoroughly until the water runs clear to remove excess starch for a cleaner broth.
- 2Skim the froth that rises during boiling to keep the soup clear and prevent a muddy texture.
- 3Whisk the soup vigorously after cooking to break down the lentils into a silky, uniform base without needing a blender.
- 4Adjust soup consistency with hot water just before serving, as leftovers will thicken further upon cooling.
- 5Use a small tadka pan (preferably iron or steel) to evenly heat ghee and prevent burning the nigella seeds.
- 6Add lemon juice only after removing the soup from heat to retain its bright, fresh acidity.
- 7For a deeper tarka flavor, let the sizzling ghee mixture rest for 10 seconds before stirring into the soup.
