Why it works: Sweet potato and flour work together. They rank in the top 9% of all ingredient pairs, and cooks put them together in 627 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Prepare
Peel and cut the sweet potatoes in half.
Dredge the potatoes in equal parts of sugar and flour, and add salt.
Bake
Place the potatoes in a baking pan with melted butter and water.
Bake on a grate until both sides are a rich brown, about 30 to 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Jersey sweet potatoes
- Provide the soft, starchy body that becomes tender and sweet as it bakes.
- Sugar
- Adds sweetness and caramelizes into a glossy, browned coating.
- Flour
- Coats the potatoes so the sugar and butter cling to the surface.
- Melted butter
- Adds fat and richness, helping the surface brown evenly in the oven.
The step that matters
Judge the browning, not just the clock. Sugar darkens quickly and can scorch, while the potato interior is still softening. Watch for a rich brown on both sides, since ovens vary and the coating may color faster than the potato cooks through.
Swap the sweet potato
How well each one fits the dish's main ingredients (sugar, flour, butter):
- Arrowrootfits about as well

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