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, becoming tender and absorbing the syrup as they cook.
Brown sugar
Dissolves into the syrup and thickens as it cooks, giving the potatoes their sweet, glossy coating.
Butter
Adds fat and richness to the syrup, helping it become smooth and glossy.

The step that matters

When the syrup thickens, set the skillet aside. Sugar syrup thickens as water evaporates and it cools, and it can quickly turn grainy or hard if overcooked. Removing the skillet at the right moment keeps the glaze smooth and pourable.

Swap the sweet potato

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

  1. Sweet potatothe original
  2. Leekfits about as well
  3. Potatofits about as well
  4. Capsicumfits less well

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