Ingredients
Directions
Prepare the paste
Fry black pepper, red pulse, and carapala leaves in ghee in an iron ladle.
Grind the mixture into a fine paste.
Make the sour
Mix in tamarind pulp and fresh water, then bring to a boil 2-3 times.
Fry mustard, cumin, and fenugreek seeds in ghee, then add to the boiling mixture.
Add the second variation
For a second variation, fry another ½ ounce of black pepper and red pulse in ghee.
Grind and mix with water, then add salt and lime juice.
Boil as before, adding fried cumin, mustard, fenugreek, and carapala leaves.
If desired, add moringa fruit or wood apple shells for fragrance.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black pepper
- Provides the main pungent heat and aroma that defines the sour.
- Red pulse
- Adds body and earthy flavour to the paste, thickening the broth slightly when ground.
- Ghee
- Carries the spices' flavour and gives a rich, fatty aroma when frying.
- Tamarind pulp
- Supplies the sourness and tang that gives the sour its character.
- Mustard seeds
- Release nutty, pungent aroma when fried in fat, adding a finishing flavour.
- Cumin seeds
- Release warm, earthy aroma when fried in fat, adding depth to the broth.
The step that matters
Frying the seeds in ghee. Mustard, cumin and fenugreek seeds need brief frying in hot fat to release their aromatic oils. Overheating them can scorch and turn them bitter, so they should be fried just until fragrant.
Swap the apple
The recipe marks apple as optional. How well each one fits the dish's main ingredients (pepper, ghee, tamarind, mustard, cumin, fenugreek, lime):
