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 ↓
Harrison Cake
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 300°F (150°C).
Make the batter
In a large bowl, cream the butter and molasses together.
Add the eggs one at a time, mixing well after each addition.
Stir in the flour, baking soda, and spices until combined.
Fold in the raisins.
Pour the batter into deep pans.
Bake
Bake for 3 hours or until a toothpick comes out clean.

Flour and butter 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 cake together as it bakes.
- Molasses
- Adds sweetness, moisture, and a dark color to the batter.
- Butter
- Adds richness and tenderness through fat creamed into the batter.
- Eggs
- Bind the batter and add structure and moisture as they set.
- Baking soda
- Reacts with the acidity in the batter to help it rise.
- Raisins
- Add chewy texture and concentrated sweetness throughout the cake.
The step that matters
Bake until a toothpick comes out clean. A long bake at low heat sets the batter gradually. Pulling it early leaves the centre wet and gummy, while over-baking dries the cake out.
