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 ↓
Ginger Fruit 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.
Prepare the oven
Preheat your oven to 300°F (150°C).
Make the batter
Cream together the butter and sugar.
Add the beaten eggs, ginger, cinnamon, molasses, and flour, then stir well.
Flour the raisins and currants.
Fold the raisins and currants into the mixture along with the baking soda.
Bake
Line your pan with several layers of buttered paper.
Pour the batter into the pan and bake.

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
- Adds richness and a tender crumb by coating flour and trapping air when creamed with sugar.
- Sugar
- Sweetens the cake and helps trap air when creamed, contributing to a light texture and browning.
- Eggs
- Bind the batter and add structure as they set during baking.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Molasses
- Adds moisture, deep sweetness, and dark color to the cake.
- Baking soda
- Reacts with the acidic molasses to produce gas that helps the cake rise.
The step that matters
Flouring the raisins and currants. Dusting the fruit with flour helps it cling to the batter, so the heavy pieces are less likely to sink to the bottom of the cake while it bakes.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour, egg, molasses, raisin, ginger):

- Currantthe original
Fit is the average pairing score against sugar, butter, flour, egg, molasses, raisin, ginger. Candidates are from the same food group and used in at least 100 recipes.
