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 ↓
White Sponge Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Mix and bake
In a bowl, combine the powdered sugar, cream of tartar, and flour.
Stir in the egg whites and lemon juice until well mixed.
Pour the batter into a prepared cake pan and bake immediately.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Provide the main structure and airy lift as the cake sets in the oven.
- All-purpose flour
- Forms the gluten and starch framework that holds the cake's shape once baked.
- Powdered sugar
- Adds sweetness and a fine, tender crumb because it dissolves easily.
- Cream of tartar
- Acidifies the egg whites, helping them hold their structure and resist collapsing.
- Lemon juice
- Adds acidity and bright flavor while also helping stabilize the egg whites.
The step that matters
Bake immediately after mixing. The air trapped in the egg white batter starts to escape once it sits, so delaying the oven can leave the cake flatter and denser.
Swap the lemon
How well each one fits the dish's main ingredients (egg, coffee, flour, sugar, cream):

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