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

What each ingredient does

Grated raw potato
Provides the starchy body that thickens the filling as it bakes.
Sweet milk
Forms the liquid base that carries the custard and softens the potato.
Eggs
Set the mixture into a custard-like filling as they cook.
Sugar
Adds sweetness and helps browning on the exposed surface.
Butter
Adds fat for richness and a softer, smoother texture.

The step that matters

Let the mixture cool before adding the eggs. Eggs added to very hot milk can scramble or curdle instead of blending smoothly. Cooling the mixture first lets the eggs combine evenly, so the filling sets into a smooth custard.

Swap the potato

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

  1. Potatothe original
  2. Sweet potatofits about as well
  3. Asparagusfits about as well
  4. Capsicumfits about as well

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