Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Winter Sponge Cake
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat your oven to 400°F (200°C).
Make the batter
In a large bowl, beat the eggs until frothy.
Gradually add the sugar, mixing well.
Sift in the flour and cream of tartar, and mix until combined.
Add the boiling water and lemon flavor, stirring gently.
Bake
Pour the batter into a pan and bake in the preheated oven.

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 sponge its light, airy structure.
- Sugar
- Sweetens the cake and helps the beaten eggs hold their foam.
- All-purpose flour
- Provides the starch and gluten that set the cake's structure as it bakes.
- Cream of tartar
- Acidifies the batter, stabilizing the egg foam and supporting a tender crumb.
- Boiling water
- Adds moisture and helps the batter spread and bake into a soft sponge.
The step that matters
Add the boiling water and lemon flavor, stirring gently.. Stirring too vigorously deflates the whipped egg foam that gives a sponge its rise, leaving a dense cake. Gentle folding keeps the air in the batter.
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.
