The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Eggs
Trap air when beaten, giving the drops a light, airy structure.
Sugar
Sweetens the batter and helps stabilize the beaten egg foam.
All-purpose flour
Provides the starch and gluten that set the drops into a soft structure.
Cream of tartar
Acidifies the batter and stabilizes the egg foam against collapsing.
Baking soda
Reacts with the acid in the batter to release gas that helps the drops rise.

The step that matters

Beat the eggs and sugar until frothy. Eggs and sugar must be beaten long enough to form a stable foam. This trapped air is what lifts the drops. Under-beaten eggs leave the drops dense and flat.

Swap the lemon

How well each one fits the dish's main ingredients (egg, sugar, coffee, flour, cream):

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