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 ↓
Blueberry Cake
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
In a mixing bowl, cream together the sugar and butter.
Add the sweet milk and egg, and mix well.
In a separate bowl, combine the flour and baking powder.
Make the batter
Gradually add the dry ingredients to the wet mixture, stirring until combined.
Fold in the blueberries that have been rolled in flour.
Pour the batter into a greased baking pan.
Bake and serve
Bake for 30 minutes or until a toothpick comes out clean.
Serve warm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the main structure that sets as the cake bakes.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Egg
- Binds the batter and adds structure as it sets.
- Baking powder
- Releases gas that lifts the batter as it bakes.
- Sugar
- Sweetens the cake and helps it brown at the edges.
- Blueberries
- Add moisture and bursts of fruit flavour through the crumb.
The step that matters
Folding in the flour-coated blueberries. Dusting the berries in flour helps suspend them so they do not sink to the bottom. Fold gently so the batter is not overmixed, which would toughen the crumb and release the baking powder's lift too early.
