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 ↓

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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
- Flour
- Provides the structure that holds the cake together as it bakes.
- Eggs
- Egg yolks enrich and bind the batter, while whites add lift when folded in.
- Butter
- Adds richness and tenderness, and carries flavor through the crumb.
- Sugar
- Sweetens the cake and helps create a tender, browned crumb when creamed with butter.
- Baking powder
- Releases gas during baking so the cake rises and becomes lighter.
- Raisins
- Add concentrated sweetness, moisture, and chewy texture to the cake.
The step that matters
Fold in the egg whites. Whites hold air that gives the cake its lift. Folding gently, rather than beating, keeps that air from collapsing, so the cake bakes up lighter.
Swap the mace
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, raisin, currant, cinnamon):
- Nutmegfits better
- Allspicefits better
- Clovefits better
- Macethe original
Fit is the average pairing score against flour, sugar, butter, egg, raisin, currant, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
