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 Buns
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.
Make the batter
Preheat the oven to 350°F (175°C).
Beat the butter and sugar together until creamy.
Beat the eggs in a separate bowl.
Add the milk, cinnamon, and flour to the butter mixture, mixing well.
Pour the batter into a shallow pan and bake until done.
Ice and finish
For the icing, mix the egg white with a little sugar and half a teaspoon of cinnamon.
Spread the icing over the top of the baked buns.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness to the batter as it sets in the oven.
- Butter
- Adds fat and tenderness, creaming with sugar to trap air for a lighter crumb.
- Sugar
- Sweetens the batter and helps brown the surface as it bakes.
- Flour
- Forms the structure that holds the baked crumb together.
- Milk
- Adds moisture and helps the batter bind into a smooth mixture.
The step that matters
Creaming the butter and sugar. Beating butter and sugar until creamy traps air in the fat, which helps the buns rise and stay light. Under-beaten butter gives a denser result.
