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 ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat oven to 350°F (175°C).
In a bowl, cream together butter, brown sugar, and molasses.
Add sour milk and egg yolks, mixing well.
In a separate bowl, combine baking soda, cream of tartar, and flour.
Gradually add dry ingredients to wet mixture.
Fold in raisins, currants, cloves, cinnamon, and nutmeg.
Finish and bake
In another bowl, beat egg whites until stiff peaks form.
Gently fold egg whites into batter.
Pour batter into greased cake pan and bake for about 30-40 minutes or until 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
- Adds fat that tenderizes the crumb and carries flavor.
- Egg yolks
- Add richness and help bind the batter into a set structure.
- Egg whites
- Beaten to stiff peaks, they lighten the batter and give it rise.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas for rising.
- Cream of tartar
- Adds acidity that works with the baking soda to help leavening and stabilize the batter.
- Flour
- Provides the structure that sets the cake as it bakes.
The step that matters
Folding in the egg whites. Beaten whites hold air that gives the cake its lift. Stirring them in vigorously knocks that air out, so fold gently with a spatula until just combined.
Swap the raisin
How well each one fits the dish's main ingredients (butter, sugar, molasses, milk, egg, cream, flour):
- Vanillafits about as well
- Raisinthe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against butter, sugar, molasses, milk, egg, cream, flour. 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.
