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 ↓
Water Sponge Cake
Ingredients
Directions
The book says “a moderately quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Separate the egg whites and yolks.
Beat the egg whites until stiff, then beat in the yolks.
Gradually sift in the powdered sugar, mixing well.
Add the vanilla and flour, then quickly beat in the water.
Bake and serve
Pour the batter into a greased pan and bake for 30 minutes at 350°F (175°C).
Let the cake cool before serving.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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 whites trap air, giving the sponge its light, airy structure.
- Powdered sugar
- Sweetens the cake and adds fine texture as it is sifted into the batter.
- Flour
- Provides the starch that sets during baking to form the cake's structure.
- Water
- Adds moisture and loosens the batter, helping it bake up tender.
The step that matters
Beating the egg whites until stiff. Under-beaten whites will not hold enough air, so the cake may be dense; over-beaten whites turn dry and grainy and can collapse in the oven. Air bubbles in the whites are the main source of lift in a sponge.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, sugar, flour):
- Raisinfits better
- Vanillathe original
- Lemonfits less well
- Figfits less well
Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
