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 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 300°F (150°C).
Make the batter
In a large bowl, cream together the butter and brown sugar.
Add the eggs and milk, mixing well.
Gradually stir in the flour and raisins, adding spice to taste.
Bake
Pour the batter into a greased cake pan.
Bake for 3 hours or until a toothpick inserted comes out clean.

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 add richness and tenderness to the crumb.
- Brown sugar
- Adds sweetness and moisture, and its molasses gives the cake a deeper flavour.
- 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.
- Milk
- Adds moisture and helps the batter come together into a smooth mixture.
- Raisins
- Add chewy pockets of sweetness and moisture throughout the cake.
The step that matters
Baking low and slow for a long time. A low oven lets the centre cook through gently before the outside dries or darkens too much. Checking for doneness with a toothpick confirms the centre has set, since a dense batter can look browned before it is fully baked.
Swap the raisin
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour):
- Vanillafits about as well
- Raisinthe original
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against butter, sugar, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
