Why it works: Flour and buttermilk are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Vanilla Cake
Ingredients
Directions
Prepare
Separate the eggs, placing the whites in a medium-sized bowl and setting the yolks aside.
Beat the egg whites until they form soft peaks. Set aside.
Combine the dry ingredients in a medium-sized bowl. Set aside.
Grease and flour two 9-inch cake pans.
Make the batter
In a large bowl, cream together butter and sugar for about a minute until smooth.
Beat in the egg yolks one at a time, then add vanilla extract.
Alternately add the dry ingredients and buttermilk, sifting the dry ingredients into the batter.
Fold in the beaten egg whites.
Distribute the batter evenly among the pans.
Bake and cool
Bake at 325°F for 28–30 minutes.
Let cool in pans for 10 minutes, then transfer to a wire cooling rack and let cool completely.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and adds richness and tender texture.
- Eggs
- Yolks add richness and structure; whipped whites lighten the batter and help it rise.
- Cake flour
- Provides the starch and gluten structure that holds the cake's crumb together.
- Baking powder
- Releases gas in the batter to make the cake rise and become light.
- Buttermilk
- Adds moisture and acidity that tenderise the crumb and react with leavening.
- White sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
The step that matters
Folding in the beaten egg whites. Whites hold air only while whipped, so folding gently keeps the batter light. Overmixing or deflating them makes the cake dense and less risen.
Swap the vanilla
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, buttermilk):
- Raisinfits better
- Vanillathe original
- Lemonfits less well
- Figfits less well
Fit is the average pairing score against butter, sugar, egg, flour, buttermilk. Candidates are from the same food group and used in at least 100 recipes.
