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 ↓

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.
Prepare
Preheat the oven to 350°F (175°C).
Prepare two cake molds.
Make the batter
Cream the butter and powdered sugar together.
Add the egg yolks and grated pineapple to the mixture.
Sift the salt, baking powder, and flour together.
Quickly beat the flour into the batter.
Bake
Pour the batter into the prepared molds.
Bake until golden brown.

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 the sugar to trap air and add richness and tenderness to the crumb.
- Egg yolks
- Add richness, emulsify the batter and help bind the cake structure.
- Grated pineapple
- Adds moisture and fruity acidity to the batter.
- Flour
- Provides the main structure of the cake once it sets in the oven.
- Baking powder
- Releases gas in the batter to make the cake rise and become light.
The step that matters
Quickly beat the flour into the batter. Once flour is mixed with liquid, gluten begins to form. Beating too long or slowly can toughen the cake, so the flour should be folded in quickly and only until combined.
Swap the pineapple
How well each one fits the dish's main ingredients (butter, sugar, egg, flour):

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