Why it works: Potato and butter are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Glazed Sweet Potatoes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the potatoes
Wash and peel the potatoes.
Cook the potatoes in boiling salted water for 10 minutes.
Drain the potatoes.
Cut them in half lengthwise.
Place them in a buttered pan.
Make the syrup
Make a syrup by boiling the sugar and water for 3 minutes.
Add the butter to the syrup.
Glaze and bake
Brush the potatoes with the syrup.
Bake at 400°F (200°C) for 15 minutes, basting twice with the remaining syrup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the main body of the dish and soften into a tender interior when parboiled and baked.
- Sugar
- Dissolves into the syrup to sweeten and caramelize into a glossy glaze on the potatoes.
- Butter
- Adds richness and fat to the syrup, helping it coat the potatoes and brown.
The step that matters
Basting with the remaining syrup. Sugar in the syrup browns and thickens as it bakes, so it can scorch if left too long. Basting twice keeps the surface moist and builds an even, glossy glaze rather than a dry or burnt coating.
Swap the potato
How well each one fits the dish's main ingredients (sugar, butter):
- Sweet potatofits about as well

- Potatothe original
- Capsicumfits about as well
Fit is the average pairing score against sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
