Why it works: Raisin and flour 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 ↓
Plum Gingerbread
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 the oven to 350°F (175°C).
In a bowl, mix molasses, mace, sour milk, and eggs.
In another bowl, combine flour, baking soda, salt, and raisins.
Gradually add the dry ingredients to the wet mixture.
Pour the batter into a greased baking pan.
Bake and finish
Bake for about 30‑40 minutes or until a toothpick comes out clean.
Once cooled, cover the top with chocolate icing and flavor with vanilla.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Adds dark sweetness, moisture and the characteristic gingerbread flavor.
- Eggs
- Bind the batter and help give the crumb structure as they set in the oven.
- Baking soda
- Reacts with the acidic sour milk to release gas, helping the cake rise.
- Sour milk
- Its acidity activates the baking soda and adds tenderness and moisture.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding flour in portions and mixing gently limits gluten development, keeping the crumb tender rather than tough. Overmixing can also deflate the gas produced by the baking soda.
Swap the mace
How well each one fits the dish's main ingredients (molasses, milk, raisin, flour, egg, chocolate, vanilla):
- Cinnamonfits better
- Nutmegfits better
- Clovefits better
- Macethe original
Fit is the average pairing score against molasses, milk, raisin, flour, egg, chocolate, vanilla. Candidates are from the same food group and used in at least 100 recipes.
