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, tender body of the dish once boiled and sliced.
- Dripping or butter
- Conducts heat and adds fat, helping the slices brown in the pan.
The step that matters
Frying until light brown. Frying over heat that is too low leaves the slices greasy and pale, while heat that is too high browns the outside before the inside heats through. Potato slices that are dry on the surface brown more evenly, so draining them well before frying helps.
Swap the sweet potato
How well each one fits the dish's main ingredients (butter, pepper):
- Capsicumfits better
- Potatofits better
- Carrotfits better
- Sweet potatothe original
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
