What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Rinse the red lentils until the water runs clear to remove excess starch and prevent cloudiness.
- 2Do not skip the tempering step—cracking cumin seeds in hot oil releases their essential oils for deeper flavor.
- 3Simmer the soup with the lid partially off to allow the mustard greens to wilt without turning mushy.
- 4Use an immersion blender sparingly; 2-3 quick pulses give a creamy texture while keeping some lentil pieces intact.
- 5Taste for salt after simmering, as the mustard greens can absorb more seasoning than expected.
- 6Make ahead: the soup thickens overnight; thin with a splash of hot water or broth when reheating.
- 7For a creamier result, simmer the lentils an extra 5 minutes until they naturally break down.
