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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, mix the flour, cinnamon, and baking powder thoroughly.
In another bowl, cream the butter and sugar together.
Add the eggs and sweet milk to the butter mixture and mix well.
Combine the wet and dry ingredients until just mixed.
Bake
Pour the batter into a greased baking dish.
Bake in the preheated oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, tenderizing the crumb and carrying flavor.
- Sugar
- Sweetens the bun and helps browning on the surface.
- Eggs
- Add structure and binding, helping the batter hold together as it bakes.
- Flour
- Forms the main structure of the bun as the batter sets.
- Baking powder
- Releases gas in the batter, helping the bun rise and become light.
The step that matters
Combine the wet and dry ingredients until just mixed.. Once flour meets liquid, gluten begins to develop. Overmixing toughens the batter and can make the bun dense, so stop as soon as no dry flour remains.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
