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 oven to 350°F (175°C).
In a large bowl, cream shortening and sugar together.
Add molasses, salt, and mixed spices, and mix well.
Dissolve baking soda in 1-2 cups of water and add to the mixture.
Gradually add flour until batter is quite thick.
Fold in chopped citron, raisins, and currants.
Bake
Pour batter into two medium-sized loaf pans.
Bake for about 45-60 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shortening
- Creaming with sugar traps air and gives the cake a tender, fine crumb.
- Molasses
- Adds moisture, dark color, and a deep, slightly bitter sweetness.
- Baking soda
- Reacts with the acidic molasses to release gas, helping the cake rise.
- Flour
- Forms the structure that holds the batter and fruit together as it bakes.
- Citron
- Provides chewy texture and concentrated candied-fruit flavor throughout the cake.
The step that matters
Adding the baking soda and gradually adding flour. Baking soda needs to be dissolved and mixed in evenly so it reacts with the molasses and lifts the batter. Adding flour gradually keeps the batter smooth and prevents lumps, so the structure forms evenly.
Swap the currant
How well each one fits the dish's main ingredients (sugar, molasses, flour, raisin):
- Vanillafits better
- Figfits better
- Datesfits better
- Currantthe original
Fit is the average pairing score against sugar, molasses, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
