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 gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Cream together the sugar and butter.
Beat in the egg yolks until smooth.
Dissolve the baking soda in the sweet milk and add to the mixture.
Incorporate enough flour to form a cake batter and mix in the cream of tartar.
Fold and bake
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter.
Add the blueberries or huckleberries just before pouring into the baking pan.
Bake in a hot oven at 400°F (200°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat for a tender crumb and rich flavor.
- Egg yolks
- Add richness and help bind the batter into a smooth, cohesive mix.
- Egg whites
- Whipped to stiff peaks, they trap air that lightens the cake as it bakes.
- Baking soda
- Reacts with the acidic cream of tartar to release gas and help the cake rise.
- Cream of tartar
- Acidic ingredient that reacts with baking soda and stabilizes the whipped egg whites.
- Flour
- Provides the structure that holds the cake together as it sets.
The step that matters
Folding in the egg whites. Stirring vigorously deflates the whipped egg whites and removes the air that lifts the cake. Gentle folding keeps the batter light so it rises evenly in the oven.
