Why it works: Raisin and flour 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.
Make the batter
Cream the butter and sugar together in a bowl.
Add the sour milk, ensuring the baking soda and salt are dissolved in it.
Mix in the flour combined with the spices, currants, and raisins. Mix thoroughly until well combined.
Bake
Pour the batter into a greased baking pan and bake at 350°F (175°C) until a toothpick comes out clean.

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
- Sugar
- Sweetens the cake and helps create a tender, lightly structured crumb when creamed with butter.
- Butter
- Adds fat for richness and a tender texture when creamed with the sugar.
- Sour milk
- Provides moisture and acidity that reacts with the baking soda to help the cake rise.
- Baking soda
- Reacts with the acidic sour milk to produce gas that makes the cake rise.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Raisins
- Add chewy texture and natural sweetness throughout the cake.
The step that matters
Dissolving the baking soda in the sour milk. Baking soda needs an acid to react and release gas. If it is not fully dissolved and evenly distributed in the sour milk, the cake may rise unevenly or have pockets of bitterness.
Swap the raisin
How well each one fits the dish's main ingredients (sugar, milk, butter, flour):
- Vanillafits better
- Raisinthe original
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against sugar, milk, butter, 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.
