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 ↓
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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, mix together the eggs, sugar, butter, flour, sifted meal, brandy, allspice, and baking soda.
Combine the baking soda with the sweet milk and add to the mixture.
Just before baking, gently fold in the whortleberries dusted with flour.
Bake
Pour the batter into a greased cake pan and bake until golden brown.

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 they set during baking.
- Flour
- Forms the main structure of the cake as its starches set.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Sugar
- Sweetens the cake and contributes to browning in the oven.
- Baking soda
- Reacts with the batter's acidity to produce gas that helps the cake rise.
- Whortleberries or blueberries
- Add juicy pockets of fruit that release moisture and flavor into the batter.
The step that matters
Folding in the whortleberries. Fold them in gently and only just before baking. Overmixing breaks the batter's air and gluten structure, and dusting the berries with flour helps keep them suspended rather than sinking to the bottom.
Swap the allspice
How well each one fits the dish's main ingredients (egg, sugar, butter, flour, brandy, milk):
- Cinnamonfits better
- Nutmegfits better
- Clovefits about as well
- Allspicethe original
Fit is the average pairing score against egg, sugar, butter, flour, brandy, milk. Candidates are from the same food group and used in at least 100 recipes.
