What each ingredient does
- Sweet potatoes
- Provide the starchy base that mashes into the dish's main body and texture.
- Butter
- Adds fat and richness, and helps the mash turn smooth and silky.
The step that matters
Mashing in the butter until smooth. Cooked starch breaks down into a smooth texture when mashed while warm. Adding butter in small pieces lets it melt and blend evenly, so lumps and greasy pockets are less likely.
