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

What each ingredient does

Sweet potato
Adds moisture, body, and a soft, tender texture to the batter.
Flour
Provides the structure that holds the waffle together as it cooks.
Butter
Adds fat for richer flavor and a tender crumb, and helps the surface brown.
Sugar
Adds sweetness and helps the surface brown in the hot iron.
Milk
Supplies the liquid that hydrates the flour and makes the batter pourable.

The step that matters

Bake the batter immediately in a hot waffle iron. Heat sets the outside quickly so it crisps and browns while the inside cooks through. If the batter waits or the iron is not hot enough, the waffle can steam, turn pale, and stick or cook unevenly.

Swap the sweet potato

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

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

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