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
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
In a separate bowl, combine the flour and baking soda.
Gradually add the flour mixture to the butter mixture, alternating with the rose water.
Fold in the chopped raisins.
Bake and finish
Divide the batter into three layers and bake for 20-25 minutes.
Cool the layers and frost or layer with jelly between them.

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
- Butter
- Creams with the sugar to trap air and add richness and tenderness.
- Eggs
- Bind the batter and add structure and moisture as the cake sets.
- Flour
- Forms the structure of the cake as it sets in the oven.
- Baking soda
- Reacts with the batter to help the layers rise and lighten.
- Chopped raisins
- Add chewy texture and pockets of sweetness throughout the cake.
The step that matters
Add the flour mixture gradually, alternating with the rose water. Adding flour in portions with liquid keeps the batter smooth and evenly emulsified. Adding it all at once can overmix the gluten and make the cake tough.
Swap the raisin
How well each one fits the dish's main ingredients (butter, sugar, flour, rose, egg):
- Raisinthe original
- Vanillafits about as well
- Lemonfits less well
- Figfits less well
Fit is the average pairing score against butter, sugar, flour, rose, egg. Candidates are from the same food group and used in at least 100 recipes.
