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

What each ingredient does

Sweet potatoes
Provide the starchy base that softens inside and browns on the cut surfaces.
Butter
Conducts heat for frying and adds richness and browning to the surface.

The step that matters

Fry the slices in butter until delicately browned. Starch on the cut surfaces browns through the Maillard reaction when the slices are left undisturbed in hot fat. Turning too early or using heat that is too low leaves them pale and soft rather than golden.

Swap the potato

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

  1. Capsicumfits better
  2. Potatothe original
  3. Carrotfits less well
  4. Onionfits less well

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