Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Gold Sponge Cake
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Preheat the oven to 300°F (150°C).
Beat the eggs well in a large bowl.
Gradually add the sugar to the eggs and continue beating until combined.
Mix in the water and lemon juice.
Sift together the flour, baking powder, and salt, then fold into the egg mixture.
Bake
Pour the batter into a ring pan.
Bake for 1 hour.

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 as it sets.
- Sugar
- Sweetens the cake and helps stabilize the beaten egg foam.
- All-purpose flour
- Provides the starch and gluten network that sets the cake's crumb as it bakes.
- Baking powder
- Releases gas during baking, helping the cake rise.
- Lemon juice
- Adds acidity that brightens flavor and helps stabilize the egg foam.
The step that matters
Fold in the flour mixture. Folding gently preserves the air beaten into the eggs. Stirring or deflating the batter too much produces a dense, flat cake instead of a light sponge.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, flour):

- Lemonthe original
- Figfits about as 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.
