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 that the arrowroot thickens and the eggs enrich.
Arrowroot
Thickens the hot milk into a smooth, glossy custard body.
Eggs
Set into the custard as they heat gently, giving richness and body.
Sugar
Adds sweetness to balance the savoury salt and the eggs.

The step that matters

Stirring the eggs back into the custard. Egg proteins set at around 70 to 80°C and can curdle or turn grainy if the custard gets too hot in one spot. Stirring constantly while reheating spreads the heat evenly and keeps the custard smooth.

Swap the arrowroot

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

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

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