Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Spanish Bun
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In a bowl, beat the egg and yolks together.
Make the batter
Cream the butter and brown sugar until light and fluffy.
Add the egg mixture and sweet milk, mixing well.
In another bowl, combine the flour, cream of tartar, baking soda, mixed spices, and cinnamon.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Pour the batter into a greased baking pan.
Bake
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add richness and structure as they set in the oven.
- Butter
- Adds fat and tenderness, and creaming it with sugar traps air for a lighter crumb.
- Brown sugar
- Adds sweetness and moisture, and helps the bun brown and taste deeper.
- Flour
- Provides the main structure that sets as the bun bakes.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda to help the bun rise.
- Baking soda
- Reacts with the acid in the batter to produce gas that leavens the bun.
The step that matters
Stirring the dry ingredients into the wet mixture. Gradually adding the dry ingredients and stirring only until just combined keeps the batter light. Overmixing develops gluten, which can make the bun tough and dense.
Swap the cinnamon
How well each one fits the dish's main ingredients (egg, butter, sugar, milk, flour, cream):
- Nutmegfits about as well
- Cinnamonthe original
- Capersfits less well
- Jalapenofits less well
Fit is the average pairing score against egg, butter, sugar, milk, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
