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 ↓
German Pound Cake
Ingredients
Directions
Prepare
Sift the flour into a bowl using a wire sieve.
In a separate bowl, cream the softened butter until smooth.
Add 2 teaspoons of the sifted flour, 2 teaspoons of caster sugar, and 1 egg to the butter, mixing well.
Make the batter
Gradually mix in the remaining flour, sugar, and eggs until fully combined.
Grate the lemon zest into the mixture.
Fold in the sultana raisins and chopped candied peel.
Stir all ingredients together until well combined.
Bake and cool
Line a cake tin with buttered parchment paper, placing three rounds at the bottom.
Pour the batter into the prepared tin and bake in a preheated oven at 400°F (200°C) for about 2 hours.
Once baked, turn the cake out of the tin and let it cool on its side or on a wire rack.

Flour and butter 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
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Adds richness and a tender crumb when creamed with sugar.
- Caster sugar
- Sweetens the cake and helps create a fine, tender texture when creamed with butter.
- Eggs
- Bind the batter and set during baking to give structure and richness.
- Sultana raisins
- Add chewy sweetness and moisture throughout the cake.
The step that matters
Creaming the butter until smooth. Beating softened butter with sugar traps air in the fat, which helps the cake rise and gives it an even, tender crumb. Butter that is too cold or too soft will not hold that air well.
Swap the lemon
How well each one fits the dish's main ingredients (flour, butter, sugar, raisin, egg):

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