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

What each ingredient does

Eggs
Set and thicken the filling as their proteins cook, giving it structure.
Sugar
Adds sweetness and helps give the filling a smooth, soft texture.
Butter
Adds fat for richness and a smooth, tender mouthfeel.
Crushed nuts
Provide body, texture, and nutty flavour to the filling.

The step that matters

Stirring over low heat until it thickens. Egg proteins set as they heat, which thickens the filling. If the heat is too high or stirring stops, the eggs can curdle or scramble, leaving a grainy texture instead of a smooth, thick filling.

Swap the nuts

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

  1. Almondfits better
  2. Pistachiofits better
  3. Flaxseedfits better
  4. Nutsthe original

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