Why it works: Coffee and milk are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 2,202 recipes. Both carry 4-heptenal, which smells creamy, biscuit. The science ↓
German Coffee Cake
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 300°F (150°C).
Make the batter
In a bowl, mix flour and baking soda.
Add cold coffee, molasses, sugar, sour milk, shortening, ground coffee, and ground spices to the flour mixture.
Stir until you have a stiff batter.
Toss currants with a little flour to prevent sinking, then fold them into the batter.
Bake
Pour the batter into a greased baking pan and bake slowly until done.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- All-purpose flour
- Provides the structure that holds the batter together as it bakes.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that lifts the cake.
- Molasses
- Adds dark color, moisture and a deep, slightly bitter sweetness.
- Sour milk
- Its acidity activates the baking soda and tenderizes the crumb.
- Shortening
- Adds fat that keeps the crumb tender and moist.
- English currants
- Add chewy pockets of fruit sweetness throughout the cake.
The step that matters
Toss the currants in flour before folding. A light coating of flour helps the currants stay suspended in the stiff batter instead of sinking to the bottom during baking.

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