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, sweet body of the dish once cooked through.
- Flour
- Forms a dry coating that crisps and browns when the slices hit hot fat.
- Lard
- Conducts heat for frying and gives the coating a crisp, golden surface.
The step that matters
Frying in hot lard until golden brown. If the lard is not hot enough, the flour coating absorbs fat and turns greasy instead of crisp. Too hot, and the outside browns before the potato centre is heated through. Steady heat gives a crisp, evenly cooked slice.
Swap the sweet potato
How well each one fits the dish's main ingredients (pepper, flour):
- Arrowrootfits better
- Okrafits better
- Spinachfits better
- Sweet potatothe original
Fit is the average pairing score against pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
