Why it works: Sugar and molasses are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Coffee 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 your oven to 350°F (175°C).
Make the batter
In a large bowl, cream together the butter and sugar until light and fluffy.
Mix in the molasses and cold coffee until well combined.
Stir in the currants, baking soda, mixed spices, and eggs.
Gradually add flour until the batter thickens to your desired consistency.
Bake
Pour the batter into a greased baking pan and bake for 30-40 minutes or until a toothpick 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
- Butter
- Creams with sugar to trap air, giving the cake a light, tender crumb.
- Sugar
- Sweetens the cake and helps create a light texture when creamed with butter.
- Molasses
- Adds moisture, deep sweetness and a dark color to the cake.
- Eggs
- Add structure and help bind the batter as it bakes.
- Baking soda
- Reacts with the acidic molasses to produce gas that helps the cake rise.
- Flour
- Provides structure and thickens the batter to the desired consistency.
The step that matters
Adding the baking soda with the molasses. Baking soda needs an acid to react and produce rising gas. Molasses supplies that acidity, so the batter should be mixed promptly and baked soon after the leavener is added to keep the rise strong.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, molasses, coffee, egg, flour):

Fit is the average pairing score against butter, sugar, molasses, coffee, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
