Why it works: Sweet potato and sugar are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 1,151 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Baked Sweet Potatoes
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
Boil, peel, and slice the sweet potatoes.
Layer and bake
Layer the sweet potatoes in a baking dish, covering each layer with brown sugar and pieces of butter.
Bake in a 350°F (175°C) oven until nicely browned.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Form the soft, starchy body of the dish once cooked through.
- Brown sugar
- Sweetens the dish and caramelises on the surface as it bakes, adding browning.
- Butter
- Adds fat and richness, helping the sugar melt and coat the potatoes.
The step that matters
Bake until nicely browned. Sugar caramelises and browns only at high enough heat over time. Too little baking leaves the topping pale and syrupy, while too long can burn the sugar before the potatoes are fully tender.
Swap the sweet potato
How well each one fits the dish's main ingredients (sugar, butter):
- Sweet potatothe original
- Leekfits about as well
- Potatofits about as well
- Capsicumfits less well
Fit is the average pairing score against sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
