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

What each ingredient does

Sweet potato
Provides the bulk and body of the filling, along with its sweet flavour and smooth texture.
Eggs
Set during baking, giving the filling structure so it firms into a sliceable custard.
Milk
Adds liquid that loosens the batter and contributes to a smooth, creamy texture.
Syrup or molasses
Adds sweetness and a deep, caramel-like flavour to the filling.
Butter
Adds richness and fat, contributing to a tender texture and flavour.

The step that matters

Keep the batter not too thin. Adding too much milk thins the batter, so the eggs have less protein-rich structure to set against. The filling may then stay loose or weep when baked. Adding milk gradually until the batter is smooth but not runny helps it set firmly.

Swap the sweet potato

How well each one fits the dish's main ingredients (milk, cinnamon, syrup, allspice, egg, clove, butter):

  1. Sweet potatothe original
  2. Arrowrootfits about as well
  3. Capsicumfits less well
  4. Shallotfits less well

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