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

What each ingredient does

Arrowroot or cornstarch
Thickens the milk and sugar mixture into a smooth sauce as it heats.
Milk
Forms the liquid base of the sauce.
Sugar
Sweetens the sauce and adds body to the liquid.
Rum
Adds aroma and flavour to the finished sauce.

The step that matters

Adding the arrowroot mixture to the boiling milk. Starch must be fully dispersed in cold liquid first, then stirred constantly into the hot mixture. Otherwise it clumps instead of thickening evenly into a smooth sauce.

Swap the arrowroot

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

  1. Capsicumfits better
  2. Sweet potatofits better
  3. Potatofits about as well
  4. Arrowrootthe original

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