Sweet Potato Waffles

Ingredients

• 1 1/2 cups sweet potatoes, peeled and cubed
• 1 cup whole milk
• 1/4 cup light brown sugar
• 4 tablespoons unsalted butter, melted
• 1 tablespoon orange zest
• 2 cups all-purpose flour
• 1 tablespoon baking powder
• 1/2 teaspoon kosher salt
• 6 large egg whites, at room temperature

Instructions

1. 1

   Place sweet potatoes in a steamer basket and place the basket in a large pot of simmering water. The water should beat least 2 inches from the bottom of the basket. Cover and steam over medium-high heat until the sweet potatoes are fork-tender, about 20 minutes.

2. 2

   Remove steamer basket, pour the water out of the pot, and dump the sweet potatoes into the still-hot pot. Mash with a potato masher until mostly smooth.

3. 3

   In a large mixing bowl, combine the sweet potatoes, milk, brown sugar, butter, and orange zest with a wooden spoon.

4. 4

   Sift together the flour, baking powder, and salt, and add to the sweet potato mixture. Stir to incorporate, but do not overmix; there should be lumps remaining in the batter.

5. 5

   In a separate bowl, using an electric hand mixer, beat the egg whites until stiff peaks form. Fold the egg whites into the batter one third at a time. The batter will be thick. Using a disher (appropriate to your waffle iron's capacity), dose the batter onto a heated, oiled waffle iron, and cook until lightly browned, 5 to 6 minutes. Serve hot, if you know what's good for you.
