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 ↓
Blueberry 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 the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the molasses and rich milk.
In a separate bowl, combine the cream of tartar and baking soda.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Gently fold in the blueberries.
Bake
Pour the batter into a greased cake pan and bake for 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
- Butter
- Creams with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Add structure and richness, binding the batter as the cake sets.
- Cream of tartar
- Acidic partner to baking soda, helping the cake rise and keep a light texture.
- Baking soda
- Reacts with the acidic ingredients to release gas, leavening the cake.
- Molasses
- Adds sweetness, moisture and a deep, caramel-like flavor.
- Blueberries
- Add moisture, flavor and bursts of fruit through the cake.
The step that matters
Fold in the blueberries gently. Overmixing develops gluten and toughens the crumb, while vigorous stirring crushes berries and turns the batter streaky. A light fold keeps the cake tender and the fruit whole.
