Step 1

Preheat oven to 400°F. Scrub the sweet potatoes, poke a few times with a fork and roast on a foil lined baking sheet for 40 minutes or until soft and the sugars start to caramelize.

Step 2

Once the potatoes are almost done, melt the butter in a small pan over medium heat, swirling occasionally until it turns brown and smells nutty. Keep an eye on it so it doesn't burn. Keep warm.

Step 3

When the sweet potatoes are cooked and cool enough to handle, remove the skins and add to a large mixing bowl. Add the milk, spices and salt.

Step 4

Using an electric or handheld whisk, whip the sweet potatoes until light and fluffy. Place the warm sweet potatoes in a serving bowl and top with the brown butter just before serving. Serve warm.
