Why it works: Sweet potato and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 1,015 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Baked Sweet Potatoes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Prepare and bake sweet potatoes until soft, testing by gently pressing them.
If the potatoes are old and watery, peel, parboil, and drain them.
Bake
Place the potatoes in a baking pan with a little butter or beef dripping.
Sprinkle with pepper and coarse sea salt, then bake until a fork easily pierces the largest potato.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 flesh that turns soft and sweet as it bakes.
- Butter or beef dripping
- Adds fat that carries flavour and helps the skins brown and feel rich.
The step that matters
Testing for doneness with a fork. Sweet potatoes can look done outside while the centre stays firm. Starch only becomes soft and creamy once it is fully cooked through, so testing the largest potato ensures even tenderness.

Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
