Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Pound Cake
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Stir the butter and powdered sugar together until well combined.
Add the eggs one at a time, stirring gently after each addition.
Gently fold in the flour and lemon raspings.
Bake
Optionally, add currants, raisins, preserved peel, or caraway seeds before baking.
Bake in small round pans lined with paper at 400°F (200°C) for about 25-30 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 and give the cake a rich, tender crumb.
- Eggs
- Add structure as they set and help bind the batter together.
- Flour
- Forms the cake's main structure once baked.
- Powdered sugar
- Sweetens the cake and helps create a fine, even texture when creamed with butter.
- Lemon raspings
- Add bright citrus aroma and flavor to the cake.
The step that matters
Adding the eggs one at a time. Adding eggs gradually, with gentle stirring after each, lets the emulsion form without breaking. A broken batter can bake up coarse or dense.
Swap the currant
The recipe marks currant as optional. How well each one fits the dish's main ingredients (butter, sugar, egg, flour, lemon):
- Raisinfits better
- Vanillafits better
- Figfits better
- Currantthe original
Fit is the average pairing score against butter, sugar, egg, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
