Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Cook the chicken
Cook the fowl in the stock until tender.
Remove the fowl and shred the meat.
Make the soup
Add the minced ham, lemon juice, sugar, pepper, and salt to the stock.
Mix the potato flour with a little water to make a paste, then stir it into the soup.
Add the shredded fowl and curry powder, and simmer for 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowl
- Provides the main meat and flavour, becoming tender as it cooks in the stock.
- Minced ham
- Adds savoury, salty meat flavour to the soup.
- Potato flour
- Thickens the soup as its starch swells when heated.
- Curry powder
- Adds warm, aromatic spice flavour to the soup.
The step that matters
Stirring in the potato flour paste. Potato flour must be mixed smoothly with water before adding, otherwise it forms lumps that do not disperse. Starch thickens the soup as it heats, so the soup should be simmered gently after thickening to keep the texture smooth.
Swap the potato
How well each one fits the dish's main ingredients (ham, lemon, sugar, pepper, flour):
- Arrowrootfits better
- Okrafits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against ham, lemon, sugar, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
