Why it works: Sweet potato and lime match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 177 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Fritters of Sweet Potatoes
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Peel and slice the sweet potatoes.
Marinate the slices in brandy and lime juice for 30 minutes.
Batter and fry
In a bowl, mix flour and water to create a batter.
Dip the marinated sweet potato slices in the batter.
Heat oil in a pan and fry the battered slices until golden brown.
Drain on paper towels before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Form the main body of the fritter, becoming soft and sweet inside as they cook.
- All-purpose flour
- Forms the batter that coats the slices and crisps into a golden crust when fried.
- Lime juice
- Adds acidity that brightens the flavor of the sweet potato.
- Brandy
- Adds aroma and flavor to the sweet potato slices during marinating.
The step that matters
Frying the battered slices until golden brown. The oil must be hot enough to set the batter quickly. If it is too cool, the batter absorbs oil and turns greasy instead of crisp, and the sweet potato inside may stay undercooked.
