Why it works: Lemon and peach work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 947 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

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 the batter
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Gradually add the sifted flour, mixing until just combined.
If desired, fold in lemon rind, citron, peaches, or dates.
Bake
Pour the batter into a greased loaf pan.
Bake for 50-60 minutes or until a toothpick inserted in the center comes out clean.

Butter and flour 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
- Butter
- Creams with sugar to trap air, giving the cake a tender, rich crumb.
- Granulated sugar
- Sweetens the cake and helps hold air when creamed with butter.
- Eggs
- Add structure and richness, and bind the batter as they set in the oven.
- Sifted flour
- Provides the main structure that sets as the cake bakes.
The step that matters
Adding the eggs one at a time. Beating each egg fully into the creamed butter and sugar keeps the emulsion stable. If the eggs are added too fast, the batter can curdle, which may lead to a coarser, denser texture.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (butter, sugar, egg, flour, peach, dates):
- Vanillafits better
- Figfits better
- Apricotfits better
- Lemonthe original
Fit is the average pairing score against butter, sugar, egg, flour, peach, dates. Candidates are from the same food group and used in at least 100 recipes.
