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 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, cream together the sugar and butter until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the sweet milk and molasses, then dissolve the baking soda in the molasses before adding it to the mixture.
Gradually mix in the flour until well combined.
Fold in the raisins and spices to taste.
Bake
Pour the batter into a greased baking pan and bake for about 1 hour or until a toothpick inserted in the center comes out clean.

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
- Butter
- Creamed with sugar to trap air, giving the cake a light, tender crumb and rich flavor.
- Eggs
- Add structure and richness, binding the batter as it sets in the oven.
- Baking soda
- Reacts with the acidic molasses to produce gas, helping the cake rise and darken.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Molasses
- Adds moisture, dark color and a deep sweetness, and reacts with the baking soda.
- Raisins
- Add pockets of concentrated sweetness and chewy moisture throughout the cake.
The step that matters
Dissolving the baking soda in the molasses. Baking soda needs an acid to release carbon dioxide efficiently. Dissolving it fully in the acidic molasses before adding it spreads the reaction evenly, so the cake rises uniformly rather than developing pockets or a bitter, soapy taste.
Swap the raisin
How well each one fits the dish's main ingredients (sugar, butter, egg, milk, molasses, flour):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Peachfits less well
Fit is the average pairing score against sugar, butter, egg, milk, molasses, flour. Candidates are from the same food group and used in at least 100 recipes.
