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 ↓
Plain Fruit Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together.
Add the beaten egg yolks, cinnamon, and vanilla.
Mix in the sour cream, flour, and lukewarm water with the baking soda dissolved.
Fold in the walnuts and raisins.
Optionally, add a few finely chopped figs.
Bake and finish
Pour the batter into a loaf pan and bake for about 45 minutes at 350°F (175°C).
Use any icing if desired.

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 tender texture.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Egg yolks
- Add richness, emulsify the batter, and help bind the crumb.
- Sour cream
- Adds moisture and acidity, which keeps the crumb tender and reacts with the baking soda.
- Flour
- Provides the structure that sets the cake as it bakes.
- Baking soda
- Reacts with the sour cream's acidity to produce gas that helps the cake rise.
The step that matters
Dissolve the baking soda before mixing it in. Baking soda must be fully dissolved in the liquid so it reacts evenly with the sour cream's acid. Undissolved pockets can leave bitter spots and uneven rising.
Swap the walnut
How well each one fits the dish's main ingredients (butter, sugar, egg, cream, flour, cinnamon, raisin):

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