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.
Make the batter
Beat together the egg and sugar.
Add the melted butter and milk, and mix well.
Stir in the sifted flour, salt, and baking powder until combined.
Gently fold in the blueberries.
Bake
Pour the batter into two greased shallow pans.
Bake at 400°F (200°C) for about 35 minutes.

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 structure as the cake sets.
- Flour
- Forms the main structure of the cake crumb.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Butter
- Adds fat for tenderness and a rich flavor.
- Milk
- Hydrates the flour and adds moisture to the batter.
- Sugar
- Sweetens the cake and helps keep the crumb tender and moist.
The step that matters
Gently fold in the blueberries. Overmixing once the blueberries are added breaks the batter's air and develops gluten, making the cake dense and tough. Folding gently keeps the batter light and stops the berries from sinking or bleeding color through it.
