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 very 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).
In a bowl, cream together the butter and sugar.
Add the sweet milk and mix well.
In another bowl, combine the flour, baking soda, cream of tartar, and spices.
Gradually add the dry ingredients to the wet mixture.
Fold in the raisins and currants.
Incorporate the egg yolks until well combined.
Bake
Pour the batter into a greased cake pan.
Bake for about 1.5 to 2 hours or until a toothpick comes out clean.

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 and add richness and tender texture.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Egg yolks
- Add richness, emulsify the batter, and help bind it into a tender crumb.
- Baking soda
- Reacts with cream of tartar to produce gas that helps the cake rise.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda, helping the cake rise.
- Raisins
- Add moisture, chewiness, and sweetness throughout the cake.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding flour in portions and mixing gently keeps the batter smooth and limits gluten development, which would otherwise make the cake tough and dense.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, milk, raisin, egg, cream):

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