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
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, beat together the sugar, butter, and egg.
Add the molasses and milk, ensuring the baking soda is dissolved in the milk.
Mix in the flour and spices.
Finally, fold in the raisins and currants.
Bake
Pour the 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
- Flour
- Provides the structure that holds the cake together as it bakes.
- Egg
- Binds the batter and adds structure and richness to the crumb.
- Butter
- Adds fat for a tender texture and rich flavor.
- Sugar
- Sweetens the cake and helps give it a tender, browned crust.
- Molasses
- Adds moisture, deep sweetness, and a dark color with a robust flavor.
- Baking soda
- Reacts with the molasses acidity to help the cake rise and darken.
The step that matters
Dissolving the baking soda in the milk. Baking soda needs to be evenly dissolved so it reacts throughout the batter. Unevenly distributed soda can leave bitter, soapy patches and uneven rising.
Swap the currant
How well each one fits the dish's main ingredients (molasses, milk, sugar, butter, raisin, flour, egg):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Currantthe 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.
