The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Sweet potatoes
Form the bulk of the filling, providing body, starch and natural sweetness.
Flour
Thickens the filling as it heats, helping it set rather than run.
Sugar
Adds sweetness and helps the filling brown lightly in the oven.
Butter
Adds fat for richer flavour and a softer, silkier texture.
Water
Adds moisture so the starch can thicken the filling evenly.

The step that matters

Bake until the pie is set. Starch in the flour thickens only when heated enough, and the filling firms as it cools. Underbaking leaves a runny, soggy filling, while the pie should be judged by a set centre rather than by time alone.

Swap the sweet potato

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

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

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