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 says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the sponge
In a small bowl, soften the yeast with a little milk and add ¼ of the flour to make a sponge.
Make the dough
In a larger bowl, beat the butter, sugar, and salt with a wooden spoon.
Add the eggs one at a time, mixing in flour by spoonfuls until combined.
Incorporate the risen sponge into the dough, then add the raisins and a little milk.
Shape and bake
Grease one large or two small molds and place peeled, split almonds at the bottom.
Fill the molds halfway with dough and let it rise until it is 1 inch above the mold.
Bake in a moderate oven at 350°F (175°C) until well baked.

Flour and butter 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
- All-purpose flour
- Forms the structure that holds the dough together as it rises and bakes.
- Butter
- Adds richness and tenderness, and helps create a soft crumb.
- Eggs
- Add structure, richness, and moisture, helping the dough set as it bakes.
- Compressed yeast
- Produces gas that makes the dough rise and gives it an airy texture.
- Raisins
- Add pockets of sweetness and moisture throughout the baked cake.
The step that matters
Letting the dough rise to the mold rim. Yeast needs time and warmth to produce gas. Under-proofed dough bakes dense, while over-proofed dough can collapse or lose its shape in the oven.
Swap the raisin
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, milk):
- Vanillafits about as well
- Raisinthe original
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against flour, butter, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
