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 ↓
Ribbon 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 and mix the batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the milk, baking soda, cream of tartar, and flour until combined.
Make the dark batter and bake
Divide the batter in half; bake one half in two layers.
To the remaining batter, add molasses, 1 cup of flour, and a little baking soda.
Mix in fruit and spices to taste.
Assemble
Layer the cakes with jelly, placing the dark layer in the middle and the white layers on each side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the cake's crumb together as it bakes.
- Eggs
- Add structure and help bind the batter while adding richness.
- Butter
- Adds fat that makes the crumb tender and rich in flavor.
- Sugar
- Sweetens the cake and, creamed with butter, helps trap air for a lighter texture.
- Baking soda
- Reacts with acidic ingredients to release gas, helping the cake rise.
- Molasses
- Adds moisture, deep color, and a strong, slightly bitter sweetness to the dark layer.
The step that matters
Adding the eggs one at a time. Beating each egg in fully before the next lets the fat and liquid form a stable emulsion. Adding them too fast can make the batter look curdled and bake up with a coarser, uneven texture.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
