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 ↓
Molasses Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together.
Beat in the buttermilk and the baking soda dissolved in boiling water.
Add the molasses and beaten eggs.
Mix in the flour and spices, then fold in the raisins and currants coated with a little flour.
Stir in the brandy.
Bake and test
Pour the batter into a large roasting pan placed on a small stand.
Bake for 1 hour without opening the oven door.
Check for doneness with a corn straw or knitting needle; it should come 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, slightly bitter flavor.
- Butter
- Adds richness and tenderness, and carries flavor through the crumb.
- Sugar
- Sweetens the cake and helps create a tender, browned crumb when creamed with butter.
- Buttermilk
- Adds moisture and acidity that reacts with baking soda to lift the batter.
- Baking soda
- Reacts with the acidic buttermilk to release gas, helping the cake rise.
- Eggs
- Provide structure and binding, setting the cake as it bakes.
The step that matters
Bake without opening the oven door. Opening the door drops the oven temperature and can cause the rising batter to sink or set unevenly. Keeping the door closed lets the cake rise and set steadily, and the clean-straw test confirms it is done.
Swap the currant
How well each one fits the dish's main ingredients (molasses, butter, sugar, buttermilk, flour, raisin, egg):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against molasses, butter, sugar, buttermilk, flour, raisin, egg. Candidates are from the same food group and used in at least 100 recipes.
