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 ↓

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 butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the molasses and milk until combined.
In a separate bowl, mix the flour and baking soda.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the raisins, citron, currants, and spices.
Bake
Pour the batter into a greased cake pan.
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 and rich flavour.
- 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.
- Molasses
- Adds moisture, dark colour, and a deep, sweet, slightly bitter flavour.
- Baking soda
- Reacts with the acidic molasses to produce gas that helps the cake rise.
- Raisins
- Add pockets of concentrated sweetness and moisture throughout the cake.
The step that matters
Gradually adding the dry ingredients. Overmixing once flour meets liquid develops gluten, which makes the cake tough and dense. Stir only until the flour is just combined.
Swap the currant
How well each one fits the dish's main ingredients (egg, sugar, molasses, butter, flour, milk, raisin):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Currantthe original
Fit is the average pairing score against egg, sugar, molasses, butter, flour, milk, 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.
