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 ↓
Scotch Cake
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.
Make the batter
Cream together the sugar and butter.
Add the sweet milk and eggs, mixing well.
In a separate bowl, combine 3 cups of flour with the grated lemon rind and juice.
Stir in the raisins coated with ½ cup of flour.
Dissolve the baking soda in a little cold water and add it to the mixture.
Add the baking powder mixed with ½ cup of flour.
Bake
Pour the batter into a greased pan and bake at 350°F (175°C) until done.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Flour
- Forms the main structure of the cake as it bakes.
- Baking soda
- Reacts with the batter's acidity to produce gas that helps the cake rise.
- Baking powder
- Provides additional lift so the cake rises during baking.
- Raisins
- Add chewy pockets of sweetness throughout the cake.
The step that matters
Dissolving the baking soda in cold water. Baking soda needs to be evenly dispersed through the batter, or pockets of it can leave soapy, bitter spots and uneven rising. Dissolving it in a little water first helps it spread through the batter evenly.
Swap the lemon

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