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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Soft, starchy base that the sugar glaze and flour coating cling to.
- Brown sugar
- Melts and thickens into a sticky glaze, adding sweetness and gloss.
- Flour
- Forms a thin coating that helps the outside crisp and brown when fried.
- Butter
- Fat that carries heat evenly and adds flavor and golden browning.
- Drippings
- Animal fat that adds savory flavor and promotes browning in the pan.
The step that matters
Boil the sugar and water until thick. Sugar syrup thickens as water evaporates and concentration rises. Too little boiling leaves a runny glaze that will not cling, while overboiling makes it hard and brittle once cooled.
Swap the sweet potato
How well each one fits the dish's main ingredients (sugar, flour, butter):
- Arrowrootfits 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.
