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 ↓
Sandwich 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.
Make the batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the sweet milk and eggs, mixing well.
Combine the flour and baking powder.
Add the flour mixture to the wet mixture.
Take out 4 tablespoons of the dough and set aside.
Make the filling and bake
Mix the reserved dough with molasses, additional flour, chopped raisins, nutmeg, cinnamon, and cloves.
Pour the main batter into a greased cake pan.
Layer the filling mixture on top of the batter.
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
- Butter
- Creams with the sugar to add tenderness and a rich texture to the crumb.
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Molasses
- Adds moisture, dark color, and a deep sweetness to the filling.
- Raisins
- Add chewy pockets of sweetness and moisture to the filling.
The step that matters
Layering the filling on the batter. The filling is spread over the batter rather than fully mixed in, so it creates a dense layer inside the cake. Spreading it gently keeps the layers distinct and avoids sinking it into the batter, which would change how the cake bakes and sets.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, butter, milk, egg, flour, molasses, raisin):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Allspicefits less well
Fit is the average pairing score against sugar, butter, milk, egg, flour, molasses, raisin. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
