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 ↓
Loaf Cake
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 large bowl, mix the sour cream and sugar until well combined.
Sift the flour, baking soda, and salt together, then add to the cream mixture.
Stir in the raisins, walnuts, and eggs until just combined.
Bake
Pour the batter into a loaf pan and bake for about 50-60 minutes, 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
- Sour cream
- Adds moisture and tang, keeping the crumb tender and rich.
- Flour
- Provides the structure that sets the crumb as the cake bakes.
- Eggs
- Bind the batter and help it set into a firm, sliceable loaf.
- Baking soda
- Reacts with the acidic sour cream to produce gas that helps the loaf rise.
- Sugar
- Sweetens the batter and helps browning and a soft crumb.
The step that matters
Stir in the raisins, walnuts, and eggs until just combined. Overmixing once flour is in develops gluten, which makes the loaf tough and dense. Mixing only until no dry flour remains keeps the crumb tender.
Swap the walnut
How well each one fits the dish's main ingredients (cream, sugar, flour, raisin, egg):
- Almondfits better
- Chestnutfits better
- Pistachiofits better
- Walnutthe original
Fit is the average pairing score against cream, sugar, flour, raisin, egg. Candidates are from the same food group and used in at least 100 recipes.
