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 ↓
Loaf Cake
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.
Make the batter
Cream the butter and sugar together until light and fluffy.
Mix in the molasses and spices, then add the beaten eggs.
Dissolve the baking soda in the milk and add it to the mixture.
Dredge the raisins and citron in 1 cup of flour, then mix them into the batter along with the remaining flour.
Bake
Preheat the oven to 300°F (150°C).
Pour the batter into a loaf pan and bake for 1 hour.

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.

Flour and butter 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
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- All-purpose flour
- Forms the main structure of the cake as its proteins set during baking.
- Butter
- Adds fat for a tender crumb and carries flavour through the batter.
- Sugar
- Sweetens the cake and helps it brown while creaming aerates the butter.
- Molasses
- Adds moisture, dark colour and a rich, sweet-bitter flavour.
- Baking soda
- Reacts with the acidic molasses to produce gas that helps the cake rise.
The step that matters
Dissolving the baking soda in the milk. Baking soda must be fully dissolved and evenly distributed so it reacts with the acidic molasses throughout the batter. Unevenly mixed soda can leave bitter, soapy patches and uneven rising.
Swap the raisin
How well each one fits the dish's main ingredients (egg, flour, sugar, molasses, butter, milk):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Peachfits less well
Fit is the average pairing score against egg, flour, sugar, molasses, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
