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 ↓

What each ingredient does
- Sweet potatoes
- Form the dish's main body, becoming soft inside after boiling and browning lightly when fried.
- Dripping or butter
- Fat for frying, which carries heat to the slices and gives them a golden, rich surface.
The step that matters
Frying the slices lightly and quickly. Sweet potato slices hold a lot of sugar, so over-long or very hot frying can scorch the outside before the centre warms through. Keeping the heat moderate and the time short gives an even golden colour.
