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 Food Cake
Ingredients
Directions
The book says “a moderately slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Make the batter
Beat the egg whites to a foam, then add the cream of tartar and beat until stiff.
Gradually fold in the sugar and flour, then add the vanilla and candied cherries.
Bake and cool
Pour the batter into an unbuttered pan and bake for about 45 minutes.
If the top browns, briefly open the oven door.
Once baked, remove from the oven, invert the pan, and let it hang for 30 minutes.

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 a foam, they create the airy structure that lifts the cake.
- Sugar
- Sweetens the cake and helps stabilise the whipped egg white foam.
- Flour
- Provides structure so the cake holds its shape as the foam sets.
- Cream of tartar
- Stabilises the beaten egg whites so the foam holds its volume.
The step that matters
Folding in the sugar and flour. Folding gently keeps the air trapped in the whipped egg whites. Stirring or deflating the batter causes the cake to be dense and short.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, flour, egg, cream):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against sugar, flour, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
