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 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
In a bowl, mix sugar, sweet milk, molasses, and lard and butter until combined.
Add flour, eggs, ginger, and raisins; mix well.
Dissolve baking soda in a little hot water and add to the mixture.
Bake and store leftovers
Spoon the batter into gem pans.
Bake until golden brown.
Store any leftover batter in a cool place.

The flavor team
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
- Flour
- Provides the structure that holds the cakes together as they bake.
- Eggs
- Bind the batter and help set the cakes' structure as they bake.
- Molasses
- Adds sweetness, moisture, and the dark color and flavor of the cakes.
- Baking soda
- Reacts with the acidity in molasses to release gas that lifts the batter.
- Lard and butter
- Add fat that makes the cakes tender and rich.
- Sweet milk
- Adds moisture and helps the batter come together smoothly.
The step that matters
Dissolving the baking soda. Baking soda must be fully dissolved and evenly mixed into the batter so it reacts with the molasses acid throughout. Clumps leave pockets of bitter soda and uneven rising.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, milk, molasses, butter, flour, egg, raisin):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Allspicefits about as well
Fit is the average pairing score against sugar, milk, molasses, butter, flour, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
