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 ↓
Pine-apple and Potato Pudding
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 pulp
Press the parboiled sweet potatoes through a coarse sieve to make 1 pint of pulp.
Make the batter
Cream the sugar with the butter and the egg yolks.
Slowly mix in the sweet potato pulp while beating to keep the mixture light.
Stir in the milk, grated pineapple, and vanilla extract.
Fold in the beaten egg whites gently.
Bake and serve
Pour the mixture into a pudding dish and bake at 350°F (175°C) until set.
Serve with cream or pineapple sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potato pulp
- Provides the bulk and body of the pudding, with moisture and a soft, tender texture.
- Egg yolks
- Enrich the batter and help it set into a custard-like texture when baked.
- Egg whites
- Whipped and folded in, they add lightness and help the pudding rise and hold air.
- Sugar
- Sweetens the pudding and helps tenderize the texture.
- Milk
- Adds moisture and softness, loosening the batter so it bakes evenly.
- Butter
- Adds richness and fat, contributing to a smooth, tender crumb.
The step that matters
Fold in the beaten egg whites gently. Folding keeps the air whipped into the egg whites intact. Stirring vigorously knocks out that air, so the pudding bakes denser and rises less.
Swap the sweet potato
How well each one fits the dish's main ingredients (sugar, butter, egg, milk, pineapple, vanilla):
- Sweet potatothe original
- Capsicumfits about as well
- Arrowrootfits less well
- Potatofits less well
Fit is the average pairing score against sugar, butter, egg, milk, pineapple, vanilla. Candidates are from the same food group and used in at least 100 recipes.
