Why it works: Arrowroot and pepper work together. They rank in the top 14% of all ingredient pairs, and cooks put them together in 329 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Provides the bulk and chewy texture of the soup.
- Arrowroot
- Thickens the liquid into a smooth, glossy soup as it heats.
- Milk
- Adds richness and body to the broth.
The step that matters
Add the prepared arrowroot to the boiling liquid. Arrowroot must be dispersed in cold or thin liquid first and then stirred into boiling liquid. Added as a lump or without stirring, it clumps and thickens unevenly, so the soup ends up lumpy rather than smooth.
Swap the arrowroot
How well each one fits the dish's main ingredients (milk, pepper):
- Capsicumfits better
- Potatofits better
- Tomatofits better
- Arrowrootthe original
Fit is the average pairing score against milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
