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 ↓
Candied Sweet Potatoes
Ingredients
Directions
Prepare the potatoes
Boil the sweet potatoes with the skins on until half tender.
Remove from water, peel, and cut in halves lengthwise.
Make the syrup
In an iron skillet, combine brown sugar, butter, salt, and water.
Boil the mixture for 2-3 minutes.
Candy and serve
Lay the potatoes evenly in the skillet and continue to cook.
Frequently dip the syrup over the potatoes and turn them.
When the syrup thickens, set the skillet aside until serving.
Place the potatoes on plates and drizzle syrup over each potato.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Form the main body of the dish, becoming tender and absorbing the syrup as they cook.
- Brown sugar
- Dissolves into the syrup and thickens as it cooks, giving the potatoes their sweet, glossy coating.
- Butter
- Adds fat and richness to the syrup, helping it become smooth and glossy.
The step that matters
When the syrup thickens, set the skillet aside. Sugar syrup thickens as water evaporates and it cools, and it can quickly turn grainy or hard if overcooked. Removing the skillet at the right moment keeps the glaze smooth and pourable.
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.
