Why it works: Milk and butter 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 ↓
Whortleberry Cake
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a large bowl, mix the sour milk, saleratus, eggs, salt, sugar, and butter until well combined.
Gradually add flour until the batter is thick like pound cake.
Fold in the berries and spices.
Bake
Pour the batter into a greased cake pan and bake for about 30-40 minutes, or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Its acidity reacts with the saleratus so the cake rises and turns tender.
- Saleratus (baking soda)
- Reacts with the acidic sour milk to produce gas that lifts the batter.
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Sugar
- Sweetens the cake and helps it brown lightly at the surface.
- Butter
- Adds fat for a rich, tender crumb.
- Flour
- Builds the batter's structure so the cake holds its shape as it bakes.
The step that matters
Adding the flour. Flour should be added gradually until the batter is thick like pound cake. Too much flour makes the cake dense and dry, while too little leaves it loose and unable to hold the berries.
