Tip
Make recipe dairy-free by replacing the butter with vegan "butter" spread and the half & half for full-fat canned coconut milk.
Step 1
Place sweet potatoes in a large pot and cover with water. Cover and bring to a full boil. Boil potatoes for 15 to 20 minutes, until potatoes are very tender when poked with a fork.
