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 slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
In a large bowl, cream together the butter and sugar.
Add the eggs, molasses, and milk, mixing well.
Stir in the baking soda and spices.
Fold in the raisins and currants.
Gradually add flour until the batter reaches a thick consistency.
Bake
Pour the batter into a greased baking pan.
Bake for 1 hour and 15 minutes or until a toothpick 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
- Creams with the sugar to trap air and add richness and tenderness.
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Baking soda
- Reacts with the molasses acidity to help the cake rise and darken.
- Molasses
- Adds moisture, deep flavor, and browning to the crumb.
- Flour
- Builds the structure that holds the batter together as it bakes.
- Raisins
- Add chewy pockets of sweetness and moisture throughout the cake.
The step that matters
Adding the flour. Flour should be added gradually until the batter is thick but still pourable. Too much flour makes the cake dry and dense, while too little leaves it weak and greasy after baking.
Swap the currant
How well each one fits the dish's main ingredients (egg, sugar, butter, molasses, milk, raisin, flour):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Currantthe original
Fit is the average pairing score against egg, sugar, butter, molasses, milk, raisin, flour. Candidates are from the same food group and used in at least 100 recipes.
