Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Angel Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the egg whites to a stiff froth.
Sift the flour five times to make it very light.
Sift the powdered sugar with the flour once.
Add the cream of tartar and sift again with the sugar and flour.
Pour in the beaten egg whites and mix well.
Add the lemon or vanilla extract.
Bake and cool
Pour the batter into an angel food cake pan without greasing it.
Bake for 30 minutes at 350°F (175°C).
Once baked, turn the pan upside down on a cloth to cool.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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 stiff foam that traps air and gives the cake its rise and airy structure.
- Flour
- Provides structure once baked, holding the airy foam together as the cake sets.
- Powdered sugar
- Sweetens the cake and, being fine, blends smoothly into the batter.
- Cream of tartar
- Stabilises the whipped egg whites, helping the foam hold its volume and stay tender.
The step that matters
Pour the batter into an ungreased pan. Angel food batter has no fat and relies on clinging to the pan sides to climb while baking. Greasing the pan lets the batter slip and collapse, so the cake may fail to rise fully.
Swap the lemon
How well each one fits the dish's main ingredients (egg, flour, sugar, cream):

Fit is the average pairing score against egg, flour, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
