Why it works: Pineapple and vanilla match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 911 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Pineapple Upside Down Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the batter
Sift flour once, measure, then add baking powder, salt, and sugar; sift together three times.
Add butter to the flour mixture.
Combine egg, milk, and vanilla; add to the flour mixture, stirring until all flour is dampened.
Beat the mixture vigorously.
Make the topping
Melt 6 tablespoons of butter over low heat; add brown sugar and pineapple juice, cooking and stirring until thick.
Add the 7 slices of pineapple to the mixture and place a cherry in the center of each slice.
Bake and serve
Pour the cake batter over the pineapple mixture and bake in a moderate oven (350°F / 175°C) until done.
Turn the cake upside down on a dish with the pineapple on top.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Flour
- Forms the structure that holds the cake's crumb together.
- Baking powder
- Releases gas in the batter, making the cake rise and become light.
- Egg
- Adds structure and richness, helping bind the batter.
- Butter
- Adds fat for tenderness and flavor, and enriches the caramel topping.
- Brown sugar
- Adds sweetness and caramel flavor when cooked into the topping.
- Pineapple juice
- Adds moisture and fruity acidity to the thickened topping.
The step that matters
Turning the cake out. The butter and sugar topping hardens as it cools and can bond to the pan. Inverting the cake carefully and promptly helps the pineapple and cherries release cleanly onto the dish.
Swap the pineapple
How well each one fits the dish's main ingredients (flour, milk, butter, sugar, egg, vanilla):

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