Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Browned Sweet Potatoes
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cut cold boiled potatoes into ¼-inch thick slices.
Sprinkle with salt and pepper.
Spread with butter and sprinkle with sugar.
Brown
Place in a 400°F (200°C) oven to brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled potatoes
- Form the base of the dish, holding their shape while the surface dries and browns.
- Butter
- Carries heat across the surface and promotes browning and a rich flavor.
- Sugar
- Caramelizes in the oven, adding sweetness and deepening the browned color.
The step that matters
Placing the slices in the oven. Potato slices need enough surface dryness and direct heat to brown rather than steam. Spreading them in a single layer with space between slices lets moisture escape, which allows the butter and sugar to caramelize.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, sugar):
- Capsicumfits better
- Potatothe original
- Sweet potatofits about as well
- Mustardfits about as well
Fit is the average pairing score against pepper, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
