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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Beat in the eggs one at a time, mixing well after each addition.
Stir in the sour milk and molasses until combined.
In a separate bowl, mix the flour, baking soda, and spices.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the raisins or currants, if using.
Bake
Pour the batter into a greased baking pan and bake for about 45-50 minutes, or until a toothpick inserted in the center comes out clean.
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
- Butter
- Creams with sugar to trap air, giving the cake a light, tender crumb and rich flavor.
- Eggs
- Add structure and richness, binding the batter as it sets in the oven.
- Sour milk
- Its acidity reacts with baking soda to lift the batter and tenderize the crumb.
- Molasses
- Adds moisture, deep sweetness and a dark color to the cake.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking soda
- Reacts with the acidic sour milk and molasses to make the cake rise.
The step that matters
Stirring in the dry ingredients. Once flour meets the wet mixture, gluten begins to form. Stirring only until just combined keeps the crumb tender rather than tough and dense.
Swap the raisin
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, molasses, flour):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Peachfits less well
Fit is the average pairing score against butter, sugar, egg, milk, molasses, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
