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 ↓
Angel 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
Sift the flour and baking powder together four times.
Make the batter
Beat the egg whites until stiff peaks form.
Gradually beat in the sugar and vanilla extract.
Gently fold in the flour mixture until combined.
Bake and cool
Pour the batter into an ungreased pan and bake at 300°F (150°C) for 40 minutes.
Invert the pan to cool, placing something under the corner for air circulation.
Once cool, cut the cake out of the pan.

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
- Egg whites
- Whipped into stiff peaks to trap air, giving the cake its light, airy structure.
- Sugar
- Sweetens the cake and helps stabilise the whipped egg white foam.
- All-purpose flour
- Provides the starch and gluten that set the cake's structure as it bakes.
- Baking powder
- Releases gas during baking to help the light cake rise.
The step that matters
Gently fold in the flour mixture. Folding gently keeps the air beaten into the egg whites. Stirring or deflating the batter causes a dense, flat cake.
Swap the vanilla
How well each one fits the dish's main ingredients (flour, egg, sugar):
- Raisinfits better
- Vanillathe original
- Lemonfits less well
- Figfits less well
Fit is the average pairing score against flour, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
