Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Sponge Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the eggs in a large bowl.
Add the sugar and continue beating until well combined.
Mix in 1 cup of flour and beat until smooth.
Stir in the cold water and beat until incorporated.
Add the baking soda and beat again.
In a separate bowl, combine 1 cup of flour with the cream of tartar, then add to the mixture and beat until smooth.
Finally, mix in the vanilla extract.
Bake
Pour the batter into a greased cake pan and bake in a slow oven at 300°F (150°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and trap air when beaten, giving the cake its light body.
- Sugar
- Adds sweetness and helps keep the crumb tender and moist.
- Flour
- Forms the gluten network that gives the cake its structure as it sets.
- Baking soda
- Reacts with the acid in the batter to release gas, helping the cake rise.
- Cream of tartar
- Acts as the acid that activates the baking soda and stabilises the beaten eggs.
- Cold water
- Supplies moisture that turns the batter into a pourable mixture.
The step that matters
Add the baking soda and beat again. Baking soda reacts with the acid in the batter and starts releasing gas right away. Mix it in promptly and get the batter into the oven without delay so the bubbles are not lost before the cake sets.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, sugar, flour, cream):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against egg, sugar, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
