Ingredients

2 1/2 pounds sweet potatoes (about 5), peeled and cut into 1-inch pieces

Coarse salt

3/4 cup coconut milk

1/2 teaspoon grated lime zest plus 2 teaspoons juice

1 1/4 cups miniature marshmallows

2 tablespoons sweetened shredded coconut

Preparation

Preheat oven to 375 degrees. In a large pot, cover sweet potatoes with cold salted water by 1 inch and bring to a boil. Reduce to a rapid simmer and cook until tender, 10 to 12 minutes.

Drain potatoes in a colander and let sit 5 minutes, then transfer to a food processor and process until smooth. Add coconut milk and lime zest and juice; process until combined. Transfer mixture to a 2-quart baking dish. Top with marshmallows and coconut and bake until toasted and golden, about 15 minutes.
