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 ↓
Raisin 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, cream together the butter and sugar until light and fluffy.
Add the molasses, sour milk, and eggs, mixing well.
In a separate bowl, combine the flour, baking soda, and spices.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the raisins.
Bake
Pour the batter into a greased cake 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
- Adds fat and richness, giving the cake a tender crumb.
- Sugar
- Creaming with butter traps air and adds sweetness and browning.
- Eggs
- Bind the batter and help set the structure as it bakes.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that lifts the cake.
- Molasses
- Adds moisture, dark colour, and a deep sweet flavour.
The step that matters
Stirring the dry ingredients into the wet mixture. Once flour meets liquid, gluten begins to form. Stirring only until just combined keeps the batter tender and prevents a tough, dense cake.
Swap the clove
How well each one fits the dish's main ingredients (butter, molasses, milk, sugar, egg, flour, raisin):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits about as well
- Clovethe original
Fit is the average pairing score against butter, molasses, milk, sugar, egg, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
