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, No. I
Ingredients
Directions
The book says “a moderately quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream together the sugar and butter until smooth.
Add the beaten yolks of the eggs and mix well.
Stir in the egg whites.
Gradually add the sifted flour and mix until combined.
Bake
Pour the batter into a prepared pan.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the cake and helps tenderize the crumb when creamed with butter.
- Butter
- Adds fat for richness and a tender texture when creamed with sugar.
- Eggs (yolks)
- Add richness and emulsify the batter, helping it hold together.
- Eggs (whites)
- Add air and structure as the cake rises and sets in the oven.
- Flour
- Provides starch and protein that set the cake's structure as it bakes.
The step that matters
Mixing in the flour. Once flour is added, mixing only until combined matters. Overmixing develops gluten, which makes the cake tough and dense instead of fine and tender.
“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.
