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 says “a moderately warm oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, mix the sugar and cream until well combined.
Add the eggs one at a time, mixing well after each addition.
Sift together the flour, cream of tartar, and baking soda, then gradually add to the wet mixture.
Stir in the lemon essence.
Bake
Pour the batter into a greased cake pan and bake for 25-30 minutes or until a toothpick comes out clean.

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
- Add structure and richness, helping the batter set around trapped air as it bakes.
- Flour
- Forms the gluten network and sets the crumb structure of the cake.
- Cream of tartar
- Stabilizes the whipped air in the batter and gives a lighter, finer crumb.
- Baking soda
- Reacts with acidic ingredients to produce gas, helping the cake rise.
- Sugar
- Sweetens the cake and tenderizes the crumb while helping retain moisture.
- Cream
- Adds fat and moisture, producing a tender, rich crumb.
The step that matters
Sifting and gradually adding the dry ingredients. Adding dry ingredients in stages and mixing only until combined keeps the batter smooth and limits gluten development, which would otherwise make the cake tough. Sifting also distributes the leavening evenly so the cake rises uniformly.
