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 ↓
Ginger Sponge 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).
Cream the butter and sugar together until light and fluffy.
Add the well-beaten yolks of the eggs, then mix in the molasses and half of the sour milk and flour.
Stir in the ginger and the baking soda dissolved in the remaining sour milk.
Fold in the four well-beaten egg whites gently until combined.
Bake
Pour the batter into two greased loaf pans 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
- Eggs
- Yolks add richness and structure, while whipped whites lighten the batter and help it rise.
- Butter
- Creamed with sugar, it traps air and adds fat for a tender crumb.
- Molasses
- Adds moisture, dark colour and deep sweetness with a robust flavour.
- Sour milk
- Its acidity reacts with the baking soda to lift the cake and keep it tender.
- Baking soda
- Reacts with the acidic sour milk to produce gas that makes the cake rise.
- Flour
- Provides the structure that sets as the cake bakes.
The step that matters
Fold in the egg whites gently. Whipped whites hold the air that lightens the cake. Vigorous stirring knocks that air out, leaving a dense, flat crumb.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, butter, sugar, milk, egg, flour):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Allspicefits about as well
Fit is the average pairing score against molasses, butter, sugar, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
