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 the batter
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the sugar and butter until light and fluffy.
Add the milk, flour, eggs, cream of tartar, and baking soda. Mix until well combined.
Divide the batter into three equal parts.
To one part, add the molasses, currants, and spices. Mix well.
Bake and assemble
Pour one part of the batter into each of two greased cake pans.
Pour the spiced batter into a third greased cake pan.
Bake all three cakes until a toothpick inserted in the center comes out clean.
Once baked, layer the light cake, spread with jelly, then add the dark cake, more jelly, and top with the remaining light cake.
Cover with a paper, invert onto a plate, and place a weight on top until cool.

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
- Butter
- Creamed with sugar to trap air, giving the cake a light, tender crumb.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Flour
- Forms the cake's main structure once baked.
- Baking soda
- Reacts with the acidic cream of tartar and batter to produce gas that helps the cake rise.
- Molasses
- Adds moisture, dark colour and a deep, slightly bitter sweetness to the spiced layer.
The step that matters
Testing the bake. Cakes continue to cook from residual heat after leaving the oven, and pulling them too early can leave the centre gummy and sunken. Checking the centre with a toothpick until it comes out clean confirms the structure has set.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, milk, flour, egg, cream, molasses):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against sugar, butter, milk, flour, egg, cream, molasses. Candidates are from the same food group and used in at least 100 recipes.
