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.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the rose water and chopped raisins.
In a separate bowl, combine the flour and baking soda.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Bake and cool
Divide the batter into three equal parts and pour into greased cake pans.
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
Let the layers cool before frosting or adding 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 sugar to trap air and add richness and tender texture.
- Sugar
- Creams with butter for a light structure and adds sweetness and browning.
- Eggs
- Bind the batter and add structure as they set during baking.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Baking soda
- Reacts with the batter to produce gas that helps the layers rise.
- Chopped raisins
- Add moisture, chew and sweetness throughout the cake.
The step that matters
Mixing the dry ingredients into the wet mixture. Overmixing once flour is added develops gluten, which can make the cake tough. Mixing only until combined keeps the crumb tender.
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.
