Why it works: Flour and raisin 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
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, mix together the sugar, molasses, and shortening until well combined.
Add the eggs and mix until smooth.
In a separate bowl, combine the flour and baking soda.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the chopped raisins and cold coffee.
Bake
Pour the batter into a greased baking pan and bake for 30-40 minutes or until a toothpick comes out clean.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake together as it bakes.
- Eggs
- Bind the batter and add structure and richness to the crumb.
- Baking soda
- Reacts with the molasses and coffee to lift and lighten the cake.
- Molasses
- Adds moisture, dark color, and a deep, slightly acidic sweetness.
- Shortening
- Adds fat that tenderises the crumb and carries flavor.
- Chopped raisins
- Add chewy pockets of moisture and natural sweetness throughout the cake.
The step that matters
Stirring the dry ingredients into the wet mixture. Once flour meets liquid, gluten begins to form, so mixing only until just combined keeps the cake tender rather than tough and dense.
“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.
