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 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 the oven to 350°F (175°C).
Make the batter
In a bowl, cream together the sugar and butter until light and fluffy.
Add the sour milk, eggs, and molasses, mixing well.
In another bowl, combine the flour, baking soda, cinnamon, cloves, and grated nutmeg.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the raisins.
Bake
Pour the batter into a greased cake pan and bake for 30-35 minutes or until a toothpick comes out clean.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Adds fat that carries flavour and gives a tender crumb when creamed with sugar.
- Sugar
- Sweetens the cake and, creamed with butter, traps air that helps it rise.
- Eggs
- Provide structure and richness, setting the crumb as the cake bakes.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lifts the batter.
- Sour milk
- Adds moisture and acidity that activates the baking soda and tenderises the crumb.
The step that matters
Stirring the dry ingredients into the wet mixture. Overmixing once flour meets liquid develops gluten, which makes the cake tough and dense. Stir only until the flour is just combined.
