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

What each ingredient does

Potatoes
Provide the bulk and creamy body of the filling.
Butter
Adds richness and fat, giving a smooth, tender texture.
Sugar
Adds sweetness and helps the custard brown lightly as it bakes.
Eggs
Set the filling into a sliceable custard and add lift when beaten.
Milk
Adds moisture and liquid that the eggs set into a custard.

The step that matters

Stir the beaten eggs in just before baking. Beaten eggs add air and set the filling when heated. Adding them early lets them deflate and weakens the set, so they should go in just before the pie enters the oven.

Swap the potato

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

  2. Sweet potatofits about as well
  3. Asparagusfits about as well
  4. Capsicumfits about as well

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