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 ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare and mix
Preheat oven to 350°F (175°C).
Beat sugar and butter together until creamy.
Dissolve baking soda in milk, then add it with molasses to the mixture.
Gradually add sifted flour, spices, and finally the fruit.
Bake
Pour batter into shallow pans and bake for 30 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Molasses
- Adds dark color, moisture, and a deep sweet flavor to the cake.
- Butter
- Adds fat for tenderness and a rich texture when creamed with sugar.
- Sugar
- Sweetens the batter and helps create a light structure when beaten with butter.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking soda
- Reacts with the acidic molasses to produce gas that helps the cake rise.
- Egg
- Binds the batter and adds structure and richness as it sets.
The step that matters
Dissolving the baking soda in milk before adding it. Baking soda must be fully dissolved so it reacts evenly with the molasses. Clumps can leave bitter or soapy spots and uneven rising.
Swap the clove
How well each one fits the dish's main ingredients (molasses, milk, sugar, butter, raisin, flour, egg):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits about as well
- Clovethe original
Fit is the average pairing score against molasses, milk, sugar, butter, raisin, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
