Why it works: Sweet potato and lemon match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 314 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Sweet Potato Fritters
Ingredients
Directions
Prepare
Peel and slice the sweet potatoes into pieces half an inch thick and one inch wide.
In an earthen bowl, moisten the sweet potatoes with brandy and add the lemon peel.
Allow the mixture to macerate for 30 minutes.
Fry and serve
Drain the sweet potatoes, dip them in batter, and fry in hot lard until browned.
Drain the fritters and serve on a napkin, sprinkling powdered sugar over them.

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 tender inside while the batter crisps outside.
- Brandy
- Moistens the sweet potato slices and adds an aromatic, alcoholic flavour during maceration.
- Lemon peel
- Adds bright citrus aroma that complements the sweet potatoes.
- Batter
- Coats the slices and fries to a crisp, golden-brown shell.
- Lard
- Conducts heat for frying and gives the batter a rich, browned crust.
The step that matters
Fry in hot lard until browned. If the lard is not hot enough, the batter absorbs fat and turns greasy instead of crisping quickly. Frying at a steady high heat seals the coating and keeps the fritters from becoming oily.
