Mulligatawny Soup — what you need to know

Mulligatawny comes from the Tamil milagu-tannir meaning pepper-water — the British colonial adaptation of South Indian rasam into something resembling a European soup. The vegetarian version uses toor dal as its body, with coconut milk for creaminess, a South Indian spice base, and apple for a traditional Anglo-Indian sweetness. It is thicker than rasam, creamier, and more obviously filling. It is simultaneously a historical document of colonial food culture and genuinely excellent eating.

How to make it — step by step

Step 1
Cook onion, tomato and apple
⏱ 13 min

Heat oil. Cook onion until softened — 5 minutes. Add tomato, apple, turmeric, curry powder and black pepper. Cook until tomatoes break down — 8 minutes.

🔬The Science

The apple provides malic acid and natural pectin — the pectin helps body and the malic acid provides a different sourness profile from tamarind or lemon. This is the signature Anglo-Indian addition that distinguishes mulligatawny from rasam. The apple's natural sugars also caramelise with the onion, adding sweetness.

Step 2
Add dal, blend and strain
⏱ 5 min

Add cooked toor dal and stock. Blend until smooth. Strain through a medium-mesh strainer for a silky result or leave slightly textured.

🔬The Science

Toor dal provides the body — its cooked starch network thickens the soup without cream or flour. Blending integrates the dal starch uniformly through the liquid, producing a smooth, naturally thick consistency.

Step 3
Add coconut milk and finish
⏱ 7 min

Return to heat. Add coconut milk and simmer gently 5 minutes. Add salt and lemon juice. Make a mustard-curry leaf tadka and pour over.

🔬The Science

Coconut milk is an oil-in-water emulsion — its fat droplets provide creaminess and carry the spice aromatics throughout the soup. Adding it after blending rather than before prevents the fat from being destabilised by the blending process.

⚠️Common mistakes to avoid
  • Apple is optional but traditional — It adds a distinctive Anglo-Indian sweetness. Omit for a purer South Indian version.
  • Do not boil after coconut milk — Prolonged boiling breaks the emulsion and produces a grainy texture.

Why apple in an Indian soup?
Anglo-Indian colonial-era cooks adapted European soup conventions — including sweet notes from apple — into Indian spice bases. The result became its own distinct cuisine.
