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

What each ingredient does

Sweet potatoes
Form the main body of the dish, cooking through to a tender interior as they fry.
Butter
Fat that conducts heat in the pan and carries flavor, helping potatoes brown.
Brown sugar
Melts into a glaze that sweetens the potatoes and helps them caramelize.
Lemon juice
Adds acidity that brightens the sweetness and helps keep the potato flesh from browning.

The step that matters

Turning the potatoes often while glazing. Sugar burns quickly once it caramelizes in a hot pan. Frequent turning spreads the sugar evenly and keeps the glaze from darkening into bitter, burnt spots before the potatoes are tender.

Swap the sweet potato

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

  1. Arrowrootfits about as well

  4. Sweet potatothe original

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