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 ↓
Tumbler Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat your oven to 300°F (150°C).
In a large bowl, beat the eggs and mix in the sugar, butter, molasses, and milk.
Add the baking soda and spices, then stir in the raisins and currants.
Gradually add flour until the batter reaches a typical cake consistency.
Bake
Pour the batter into a greased cake pan.
Bake for 1 hour and 15 minutes, or until a toothpick inserted in the center comes out clean.

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
- Eggs
- Bind the batter and add structure as they set in the oven.
- Butter
- Adds fat and richness, giving the cake a tender crumb.
- Molasses
- Adds moisture, dark color, and a deep, slightly acidic sweetness.
- Baking soda
- Reacts with the acidic molasses to produce gas that lifts the cake.
- Flour
- Provides the main structure that sets the batter into a cake.
- Sugar
- Sweetens the cake and helps browning and a moist crumb.
The step that matters
Gradually add flour until the batter reaches a typical cake consistency. Adding too much flour at once or too much overall makes the cake dense and dry, while too little leaves it weak and wet. Adding it gradually lets you stop at the right consistency.

- Datesfits about as well
- Currantthe original
Fit is the average pairing score against egg, sugar, butter, molasses, milk, raisin, flour. Candidates are from the same food group and used in at least 100 recipes.
