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 says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 300°F (150°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
In a separate bowl, combine the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the butter mixture, alternating with the milk.
Fold in the raisins, currants, citron, and spices.
Bake
Pour the batter into a greased cake pan.
Bake for about 1.5 to 2 hours or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and add richness and tenderness to the crumb.
- Eggs
- Bind the batter and add structure and moisture as the cake sets.
- Flour
- Forms the main structure of the cake as the batter sets in the oven.
- Baking soda
- Reacts with the acidic cream of tartar to release gas that helps the cake rise.
- Cream of tartar
- Acts as an acid that activates the baking soda and helps give a tender crumb.
- Raisins
- Add chewy texture and concentrated sweetness throughout the cake.
The step that matters
Adding the dry ingredients to the butter mixture. Adding flour in alternation with milk and not all at once helps keep the batter smooth and prevents overmixing, which would make the cake tough. Mix only until combined.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, egg, milk, cream, raisin):
- Vanillafits better
- Figfits better
- Coconutfits better
- Currantthe original
Fit is the average pairing score against butter, sugar, flour, egg, milk, cream, raisin. Candidates are from the same food group and used in at least 100 recipes.
