Fried Sweet Potatoes
Ingredients
Directions
Prepare
Parboil the sweet potatoes.
Skin and cut them lengthwise into slices about ¼ inch thick.
Fry
Fry the slices in butter or sweet dripping until golden brown.
For cold boiled potatoes, chop them and mix with an equal quantity of cold Irish potatoes.
Heat the mixture in a frying pan with a good amount of butter, stirring until hot and slightly brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Provide the main body and sweetness of the dish.
- Butter or sweet dripping
- Conducts heat for frying and adds fat for browning and rich flavour.
The step that matters
Parboil the sweet potatoes before frying. Parboiling softens the starches so the slices cook through in the pan. Frying directly from raw risks a browned outside with a firm, undercooked centre.
Swap the potato
The recipe marks potato as optional. How well each one fits the dish's main ingredients (sweet potato, butter):
- Okrafits better
- Chivefits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against sweet potato, butter. Candidates are from the same food group and used in at least 100 recipes.
