Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Angel Cake, Mock
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
Sift the flour, sugar, salt, and baking powder together seven times.
Heat the milk to boiling and add the vanilla extract.
Beat the milk mixture into the dry ingredients thoroughly.
Fold in the stiffly beaten egg whites gently.
Bake and cool
Pour the batter into an ungreased pan and bake at 350°F (175°C) for about 40 minutes.
Let cool before icing.

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
- All-purpose flour
- Provides the starch and gluten framework that sets the cake's structure as it bakes.
- Granulated sugar
- Sweetens the cake and helps keep the crumb tender and moist.
- Baking powder
- Releases gas during baking so the batter rises and becomes light.
- Egg whites
- Trap air when whipped, giving the cake its airy, open structure and lift.
- Milk
- Adds moisture and helps hydrate the flour so the batter forms a smooth structure.
The step that matters
Fold in the stiffly beaten egg whites gently. Egg whites hold air bubbles that give the cake its lift. Stirring or deflating them vigorously knocks out that air, leaving a dense, flat cake.
Swap the vanilla
How well each one fits the dish's main ingredients (flour, sugar, milk, egg):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Blueberryfits less well
Fit is the average pairing score against flour, sugar, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
