Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. 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.
Make the batter
Cream the butter and sugar together.
Mix in the molasses and sour cream or milk.
Add the egg yolks and mix well.
In a separate bowl, beat the egg whites until stiff.
Fold the egg whites into the mixture.
Gently fold in the blueberries.
Sift the baking soda with the flour and gradually add it to the mixture.
Bake and serve
Pour into a greased baking pan and bake at 350°F (175°C) until a toothpick comes out clean.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites add lift and a light, airy crumb; yolks add richness and structure.
- Baking soda
- Reacts with the acidic sour cream or molasses to produce gas, helping the cake rise.
- Flour
- Forms the gluten and starch structure that holds the cake together as it bakes.
- Molasses
- Adds moisture, dark color, and a deep, slightly acidic sweetness.
- Butter
- Adds fat for tenderness and flavor.
- Blueberries
- Add moisture, tart bursts of flavor, and color throughout the cake.
The step that matters
Folding in the egg whites. Egg whites hold air only when beaten to stiff peaks; overmixing or stirring vigorously deflates them, which leaves the cake dense instead of light and airy.
