Expert Tips

Expert Tip: Be sure to season the sweet potato water with salt and pepper to develop flavor. I use ½ teaspoon each of salt and pepper.

• 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.
