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

What each ingredient does

Potatoes
Provide the starchy body that thickens the filling into a soft, sliceable custard.
Eggs
Set the filling as they cook, binding it into a firm custard.
Butter
Adds richness and a smooth, tender mouthfeel to the filling.
Milk
Forms the liquid base that the potatoes and eggs set within.

The step that matters

Add the eggs after the mixture has cooled. Eggs scrambled by hot mixture turn grainy instead of blending smoothly. Cooling the filling first lets the eggs mix in evenly and set into a smooth custard when baked.

Swap the potato

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

  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, butter, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
