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 ↓
Glazed 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
Wash and peel the sweet potatoes.
Cook them in boiling salted water for 10 minutes.
Drain and cut the potatoes in half lengthwise.
Glaze and bake
Place them in a buttered pan and baste with the syrup made from sugar, water, and butter.
Bake at 350°F (175°C) for about 25 minutes, basting twice with the remaining syrup.
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
- Provide the starchy body that softens during boiling and baking.
- Sugar
- Dissolves into the syrup and caramelizes on the surface for sweetness and browning.
- Butter
- Adds richness and helps the glaze coat the potatoes and brown in the pan.
- Water
- Dissolves the sugar into a syrup that can be spooned over the potatoes.
The step that matters
Basting with the syrup while baking. Sugar darkens quickly at oven heat, so basting with the syrup builds a glossy glaze without letting the surface burn. Spooning it over the potatoes at the set times keeps moisture on the surface while the sugars caramelize gradually.
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.
