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 ↓
Cold Water 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
Cream together the butter and brown sugar.
Beat the egg whites until stiff and fold them into the butter mixture.
Gradually add the flour and baking powder, mixing well.
Stir in the chopped raisins and spices.
Add the cold coffee and cold water, mixing until smooth.
Bake
Pour the batter into a tin lined with buttered paper.
Bake in a moderate oven at 350°F (175°C) for about 1 hour.

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 trap air and give the cake lift and a light crumb.
- Baking powder
- Releases gas in the batter and oven heat, helping the cake rise.
- Flour
- Forms the structure that sets the cake as it bakes.
- Butter
- Adds fat for tenderness and richness in the creamed base.
- Brown sugar
- Creamed with butter for sweetness and a moist, slightly molasses-flavoured crumb.
- Chopped raisins
- Add sweetness, chewy texture and moisture to the cake.
The step that matters
Folding in the beaten egg whites. Whites hold air only when beaten to stiff peaks; overmixing when folding deflates them, leaving a denser cake with less rise.
Swap the raisin
How well each one fits the dish's main ingredients (butter, flour, sugar, coffee, egg):
- Vanillafits about as well
- Raisinthe original
- Figfits less well
- Bananafits less well
Fit is the average pairing score against butter, flour, sugar, coffee, egg. Candidates are from the same food group and used in at least 100 recipes.
