Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. 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. 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 the batter
Preheat the oven to 350°F (175°C).
In a large bowl, mix the molasses, sugar, butter, and cold coffee.
Add the eggs (except for the reserved whites) and mix well.
In a separate bowl, combine the salt, baking soda, mixed spices, and enough flour to create a stiff batter.
Combine the wet and dry ingredients, then fold in the chopped raisins.
Bake
Pour the batter into two large loaf pans.
Bake for about 45‑50 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
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Molasses
- Adds moisture, deep sweetness and a dark color to the cake.
- Sugar
- Sweetens the cake and helps it brown and keep its moisture.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Baking soda
- Reacts with the molasses's acidity to lift the batter as it bakes.
- Chopped raisins
- Add chewy texture and pockets of sweetness throughout the cake.
The step that matters
Combine the wet and dry ingredients. Mixing too vigorously once the flour is added can develop gluten and make the cake tough. Stir just until combined so the baking soda stays active and the crumb stays tender.
Swap the raisin
How well each one fits the dish's main ingredients (egg, molasses, sugar, butter, coffee, flour):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Bananafits less well
Fit is the average pairing score against egg, molasses, sugar, butter, coffee, flour. Candidates are from the same food group and used in at least 100 recipes.
