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
Preheat oven to 350°F (175°C).
Make the batter
In a large bowl, mix together the molasses, sugar, butter, and milk until well combined.
Add the eggs one at a time, mixing well after each addition.
Gradually stir in the flour and ginger until the batter is smooth.
Bake
Pour the batter into a greased cake pan and bake for 30-40 minutes, or until a toothpick inserted in the center comes out clean.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Add structure and help bind the batter as it sets in the oven.
- Flour
- Forms the gluten network and structure that holds the cake's crumb together.
- Butter
- Adds fat for tenderness and a rich, soft crumb.
- Molasses
- Adds moisture, dark color, and a deep sweetness with a slight acidity.
- Sugar
- Adds sweetness and helps keep the cake moist and tender.
- Ginger
- Provides the warm, spiced aroma that defines the cake's flavor.
The step that matters
Adding the eggs one at a time. Adding eggs gradually lets each one emulsify fully into the butter and batter. Mixing well between additions prevents the batter from curdling or separating, which would leave a coarser, uneven crumb.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, butter, milk, egg, flour):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Allspicefits about as well
Fit is the average pairing score against molasses, sugar, butter, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
