Why it works: Cream and sugar 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 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the eggs until light and fluffy.
Add the sweet cream and white sugar, mixing well.
Sift in the flour, cream of tartar, and baking soda, then fold gently.
Add lemon zest to taste.
Bake
Pour the batter into a greased cake pan and bake for 25-30 minutes or until golden brown.

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
- Eggs
- Whipped to trap air, giving the cake its light, airy structure.
- Flour
- Forms the gluten network that sets the cake's structure as it bakes.
- White sugar
- Sweetens the cake and helps it brown during baking.
- Sweet cream
- Adds moisture and richness to the batter, softening the crumb.
- Baking soda
- Reacts with the acidic cream of tartar to produce gas that makes the cake rise.
- Cream of tartar
- Acidifies the batter, stabilizing the whipped eggs and reacting with baking soda to lift the cake.
The step that matters
Folding in the flour mixture. Folding gently keeps the air whipped into the eggs. Overmixing develops too much gluten, which toughens the cake and deflates the batter, reducing its rise.
