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

What each ingredient does

Flour: Provides the structure that holds the waffle together as it sets.
Egg yolk: Adds richness and helps bind the batter while it sets in the iron.
Peanut butter: Adds nutty flavour and fat, giving the waffle a tender, rich crumb.
Baking powder: Releases gas in the batter, helping the waffles rise and turn light.
Milk: Hydrates the flour and dry ingredients, making a pourable batter that cooks through.
Mini chocolate chips: Melt in the hot iron, adding sweetness and pockets of chocolate throughout.

The step that matters

Pouring the batter into a hot waffle iron. A properly preheated iron sears the outside quickly, so the waffle browns and releases cleanly. A cold iron lets the batter steam and stick, leaving a pale, soggy result.
