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 ↓
Rock Cakes
Ingredients
Directions
Prepare the dough
Put flour and sugar into a basin, then rub butter in lightly with fingers.
Add raisins, baking powder and ginger, and mix well.
Beat the egg, add two or three tablespoonfuls milk, and stir well into the other ingredients. Add more milk if necessary.
Bake
Butter a large oven tin.
Drop the mixture in spoonfuls, leaving 1‑2 inches between them.
Dust sugar over and bake 10 or 15 minutes in a quick oven.

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.

Shared aroma: beta-damascenone (apple, rose).
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
- Rubbed into flour, it coats flour particles and keeps the cakes short and tender.
- Egg
- Binds the dough together and adds structure as the cakes set in the oven.
- Baking powder
- Releases gas when heated, helping the rock cakes rise and become light.
- Sultana raisins
- Add sweetness and moisture, and bits of chewy fruit throughout the cake.
- Milk
- Adds moisture to bring the mixture together into a soft, droppable dough.
The step that matters
Adding the milk. Too much liquid makes the mixture loose and spreading, while too little leaves dry, crumbly cakes. Add milk gradually and judge the texture before adding more.
Swap the ginger
How well each one fits the dish's main ingredients (butter, milk, flour, egg, raisin, sugar):
- Cinnamonfits better
- Nutmegfits better
- Capersfits about as well

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