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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the soup and carries the other flavours.
- Flour
- Thickens the milk as it heats, giving the soup body.
- Cooked rice
- Adds bulk and a soft, starchy texture to the soup.
The step that matters
Adding the flour mixture to the boiling milk. Flour mixed with cold liquid first disperses evenly. Stirring it into hot milk while stirring constantly thickens it smoothly. Adding it dry or to unstirred milk can cause lumps that do not fully dissolve.
Swap the mace
How well each one fits the dish's main ingredients (milk, rice, flour, onion, lemon, pepper):
- Turmericfits better
- Cardamomfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against milk, rice, flour, onion, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
