What each ingredient does
- Sweet potatoes
- Provide the starchy body of the dish, becoming soft and fluffy when boiled.
- Butter
- Adds richness and moisture as it melts over the hot potato flesh.
The step that matters
Cook until easily pierced with a fork. Boiling must go on until the centre is fully tender. Undercooked starch stays firm and grainy, while thoroughly cooked starch becomes soft and smooth. Testing with a fork shows when the potato is ready.
