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 ↓
Sweet Potato Fritters
Ingredients
Directions
The book gives no oven temperature. The 400°F in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Prepare, boil, and mash the sweet potatoes.
Add the butter, flour, egg, and salt to the mashed potatoes.
Form the mixture into small round flat cakes.
Coat each cake with egg and breadcrumbs.
Fry and serve
Fry in hot fat (400°F/200°C) until nicely browned, about 4-5 minutes.
Drain well and serve with sugar and ground cinnamon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Form the bulk of the fritter and give it a soft, moist interior.
- Butter
- Adds richness and fat, contributing to flavour and a tender texture.
- Flour
- Helps bind the mashed potato so the cakes hold their shape.
- Egg
- Binds the mixture and, in the coating, helps breadcrumbs adhere.
- Breadcrumbs
- Form a crisp, golden outer crust when fried.
The step that matters
Fry in hot fat until nicely browned. Fat that is hot enough sets the breadcrumb coating quickly and browns it, so the cakes crisp outside before the interior absorbs much oil. Fat that is too cool makes the fritters greasy and soft.

Fit is the average pairing score against butter, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
