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 says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the milk and mix until combined.
In a separate bowl, combine the flour and baking powder, then gradually add to the wet mixture.
If desired, add spices, raisins, and molasses for flavor.
Bake
Pour the batter into a loaf pan or layer pans.
Bake for 30-40 minutes or until a toothpick inserted 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 sugar to trap air and give a tender, rich crumb.
- Sugar
- Sweetens the cake and, creamed with butter, helps hold air for lightness.
- Flour
- Provides the structure that sets as the cake bakes.
- Eggs
- Add structure, binding, and richness to the batter.
- Milk
- Adds moisture and loosens the batter for even baking.
- Baking powder
- Releases gas in the batter, causing the cake to rise.
The step that matters
Adding the flour mixture. Adding flour gradually and mixing only until combined keeps the batter smooth. Overmixing once flour is in develops gluten, which can make the cake tough and dense.
Swap the raisin
The recipe marks raisin as optional. How well each one fits the dish's main ingredients (butter, sugar, flour, milk, egg, molasses):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Peachfits less well
Fit is the average pairing score against butter, sugar, flour, milk, egg, molasses. Candidates are from the same food group and used in at least 100 recipes.
