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 dish and soften into a tender, spoonable texture as they stew.
Sugar
Adds sweetness and helps form a syrupy sauce as the potatoes cook.
Flour
Thickens the cooking liquid so it becomes a glossy, lightly body sauce.
Butter
Adds richness and a smooth mouthfeel to the sauce.

The step that matters

Stewing gently and stirring occasionally. Flour thickens liquid best when heated gently and stirred, since high heat can scorch the sugar and sticking can form lumps. Gentle heat keeps the sauce smooth and the potatoes intact.

Swap the sweet potato

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

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

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