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

What each ingredient does

Egg yolks
Add richness and help bind the batter while adding structure as they set.
Pastry flour
Provides the structure that holds the waffle together as it cooks.
Baking powder
Releases gas in the batter so the waffles rise and turn light.
Mashed sweet potato
Adds moisture, body, and natural sweetness to the batter.
Melted butter
Adds fat for flavor and tenderness, and helps the waffles brown.

The step that matters

Cook until golden. Waffles need enough heat and time to set their structure and brown properly. Lifting too early can tear them, while over-cooking dries them out and hardens the crust.

Swap the sweet potato

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