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 ↓
Marble 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 batters
Preheat the oven to 350°F (175°C).
In a bowl, mix the egg yolks, butter, brown sugar, molasses, sour milk, baking soda, flour, and spices until smooth.
Fold in the raisins or currants, or chocolate if using.
In another bowl, beat the egg whites until stiff.
In a separate bowl, combine corn starch, white sugar, sweet milk, butter, flour, and baking powder.
Gently fold the egg whites into the light mixture.
Bake and serve
Alternate spoonfuls of the dark and light mixtures in a baking pan.
Bake for 1 hour and 15 minutes or until a toothpick comes out clean.

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
- Egg whites
- Whipped to stiff peaks, they lighten the light batter and give the cake an airy crumb.
- Butter
- Adds fat and richness, tenderizing the crumb and carrying flavor.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Brown sugar
- Adds moisture and a caramel-like sweetness to the dark batter.
- Molasses
- Deepens the color and flavor of the dark batter and keeps it moist.
- Baking soda
- Reacts with the sour milk to produce gas that helps the dark batter rise.
The step that matters
Gently fold the egg whites into the light mixture. Whipped egg whites trap air that gives lift. Stirring vigorously knocks that air out, leaving a dense cake instead of a light, tender one.
Swap the raisin
How well each one fits the dish's main ingredients (egg, butter, sugar, molasses, milk, flour, chocolate):
- Vanillafits better
- Raisinthe original
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against egg, butter, sugar, molasses, milk, flour, chocolate. Candidates are from the same food group and used in at least 100 recipes.
