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 Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 350°F (175°C).
Beat the yolks and whites of the eggs together until well combined.
In a bowl, mix the powdered sugar, cold water, flour, baking soda, and cream of tartar.
Layer the batter in a cake pan and bake until golden.
Make the filling and topping
In a separate bowl, mix the grated pineapple with lemon juice and sweeten to taste.
Combine the beaten egg whites with 1 cup of powdered sugar and vanilla extract.
Assemble
Spread the pineapple mixture between the layers and on top of the cake.
Top with the egg white mixture.

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
- Provides the structure that holds the cake's crumb together as it bakes.
- Baking soda
- Reacts with the acid in the batter to produce gas that makes the cake rise.
- Cream of tartar
- Acidic, helping the baking soda react and stabilising the beaten egg whites.
- Eggs
- Add structure and richness, and the whites trap air for a light topping.
- Grated pineapple
- Adds moisture, fruity sweetness and a bright acidity that balances the cake.
- Powdered sugar
- Sweetens the cake and helps give the batter and topping a fine, tender texture.
The step that matters
Combine the beaten egg whites with 1 cup of powdered sugar and vanilla extract.. Egg whites must be beaten to a stable foam before the sugar is added. Adding sugar gradually and not overbeating keeps the air in the foam, so the topping stays light and does not weep or collapse.
