Why it works: Raisin and currant are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 6,180 recipes. Both carry gamma-nonanolactone, which smells coconut, creamy. The science ↓
Harrison Cake
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, mix molasses, sugar, and butter until well combined.
Add eggs one at a time, mixing well after each addition.
Dissolve baking soda in cold water and add to the mixture.
Stir in chopped raisins, dried currants, and citron.
Add spices to taste and mix thoroughly.
Bake
Pour the batter into a greased cake pan and bake for about 30-40 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
- Molasses
- Adds dark color, moisture, and a deep, sweet flavor to the cake.
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Baking soda
- Reacts with the molasses acidity to help the cake rise and darken.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Sugar
- Sweetens the cake and helps it brown during baking.
The step that matters
Dissolving the baking soda in water. Baking soda needs moisture to dissolve evenly into the batter; unevenly dispersed soda can leave pockets of bitterness or uneven rise. Mixing it fully before adding ensures a consistent crumb.

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