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 ↓
Cream 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.
Make the batter
Beat the eggs thoroughly.
Add the cream, sugar, and 1 cup of flour; mix well.
Sift the cream of tartar with ½ cup of flour and add to the mixture.
Dissolve the baking soda in 1 tablespoon of warm water and stir it in.
Add the lemon extract and mix until combined.
Bake
Pour the batter into a pan lined with parchment paper.
Bake in a preheated oven at 400°F (200°C) until done, being careful not to burn.

Flour and egg 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
- Eggs
- Beaten eggs trap air and provide structure as the cake sets.
- Flour
- Forms the gluten network that gives the cake its body and structure.
- Sugar
- Sweetens the cake and helps it brown and keep moisture.
- Sweet cream
- Adds fat and moisture, giving a softer, richer crumb.
- Cream of tartar
- Acidifies the batter and stabilizes the beaten eggs, supporting lift.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
The step that matters
Baking until done without burning. Baking soda and cream of tartar only lift the batter while it is still in the oven, so the cake must bake long enough to set its structure, yet not so long that the surface scorches. Check doneness by a toothpick test rather than by time alone.
