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 ↓
Raisin Pound Cake
Ingredients
Directions
The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and powdered sugar together.
Add the eggs one or two at a time, whipping them in with a strong egg whip.
Coat the raisins in flour, shake off the excess, and mix them in thoroughly.
Sift the flour and baking powder together, then add to the mixture and mix lightly.
Bake and finish
Bake in a cool oven at 300°F (150°C) for about two hours.
Ice the cake.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 give a rich, tender crumb.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Flour
- Forms the cake's structure once it sets during baking.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
- Sultana raisins
- Add sweetness, chewy moisture and bursts of fruit throughout the cake.
The step that matters
Mixing in the flour and raisins. Flour-coated raisins stay spread through the batter instead of sinking. Mixing the flour in lightly keeps gluten development low, so the cake stays tender rather than tough.

Fit is the average pairing score against sugar, butter, egg, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
