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 ↓
Harrison 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).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the molasses and sour milk, mixing well.
Beat in the eggs one at a time, ensuring each is fully incorporated.
Make the batter
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 inserted in the center 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.
- Eggs
- Add structure and richness, binding the batter as it sets in the oven.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that lifts the batter.
- Molasses
- Adds sweetness, moisture and a deep flavor, and helps the cake brown.
- Sour milk
- Its acidity activates the baking soda and adds tenderness to the crumb.
The step that matters
Adding the dry ingredients to the wet mixture. Stirring only until just combined keeps the batter from overdeveloping gluten in the flour, which would make the cake tough and dense.
Swap the clove
How well each one fits the dish's main ingredients (butter, sugar, molasses, milk, egg, flour, raisin):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits about as well
- Clovethe original
Fit is the average pairing score against butter, sugar, molasses, milk, egg, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
“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.
