Why it works: Pineapple and sweet potato share more aroma than cooks usually use. They rank in the top 9% of all ingredient pairs, and cooks put them together in 71 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Pineapple and Sweet Potatoes
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 the fruit and potatoes
Drain the pineapple and cut it into small pieces.
Cook the sweet potatoes until tender, then cut them into pieces.
Make the syrup
In a saucepan, cook the pineapple juice with the butter and flour until thick.
Add the sugar to the thickened mixture and stir well.
Assemble and bake
In a baking dish, mix the pineapple pieces and sweet potato pieces.
Pour the syrup over the fruit and potatoes.
Bake in a preheated oven at 350°F (175°C) until heated through and lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Provide the bulk and soft, starchy body of the casserole.
- Pineapple
- Adds sweetness and moisture, and its juice forms the base of the syrup.
- Flour
- Thickens the pineapple juice into a syrup that coats the fruit and potatoes.
- Butter
- Adds richness and fat to the syrup, giving it a smoother mouthfeel.
- Sugar
- Sweetens the syrup and helps the top brown lightly in the oven.
The step that matters
Thickening the pineapple juice. Flour must be cooked with the liquid until thick so it fully thickens the syrup. If the mixture is undercooked, the flour can taste raw and the syrup stays thin, so it will not coat the fruit and potatoes well.
