- Use fresh sweet potatoes for the best flavor.
- Slice the potatoes in even chunks so they cook evenly.
- Place the potatoes in cold water to allow them to come to a boil.
- The potatoes should be fork tender when cooked through.
- When they are fork tender, the taters will smash well and be smooth and velvety.
