Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tripe
Provides the main body and chewy texture once simmered until tender.
Milk
Forms the base of the sauce and gives it a mild, creamy richness.
Flour
Thickens the milk into a smooth sauce as it heats.
Onions
Add sweetness and aroma to the milk and blend into the finished sauce.

The step that matters

Stirring the flour paste into the milk. Flour must be mixed smooth with cold water first, then added to the milk. Adding dry flour directly causes lumps, and the starch thickens the sauce only as it heats.

Swap the onion

How well each one fits the dish's main ingredients (milk, flour):

  1. Arrowrootfits better
  2. Potatofits better
  3. Sweet potatofits better
  4. Onionthe original

Fit is the average pairing score against milk, flour. Candidates are from the same food group and used in at least 100 recipes.
