Why it works: Sweet potato and butter are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 1,491 recipes. Both carry 2,3-pentanedione, which smells butter, sweet. The science ↓
Sweet Potatoes, Boiled
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 and boil
Select sweet potatoes of uniform size.
Place them in hot water and boil until a fork easily pierces the largest one.
Dry and serve
Peel the potatoes quickly and set them in a 400°F (200°C) oven for a few minutes to dry.
Serve hot with butter.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Sweet potatoes
- Provide the main starchy body of the dish, which softens and becomes tender when boiled.
- Butter
- Adds richness and moisture to the hot potatoes as they are served.
The step that matters
Boiling until a fork easily pierces the largest potato. Testing the largest piece ensures every potato is fully cooked through, since larger potatoes take longer to soften at the center. Uniform sizes from the start help the batch cook evenly.
