Ingredients

Directions

Prepare the sweet potatoes

  1. Put cubed sweet potatoes in a steamer basket.

  2. Place the basket in a large pot of simmering water that is no closer than 2 inches from the bottom of the steamer.

  3. Allow potatoes to steam for 20 minutes or until fork tender.

  4. Mash cooked potatoes and set aside.

Make the batter

  1. In a large bowl, whisk together flour, baking powder, and salt and set aside.

  2. In another bowl combine the sweet potatoes, milk, brown sugar, butter, and grated orange rind.

  3. Stir the sweet potato mixture into the flour mixture and thoroughly combine.

  4. Beat egg whites until stiff peaks form.

  5. Gradually fold egg whites into batter ⅓ at a time.

Cook the waffles

  1. Using a no.20 disher (scoop), place 2 scoops of batter onto a preheated, oiled waffle iron, and cook until lightly browned, about 5 to 6 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sweet potatoes
Provide moisture, body and natural sweetness to the batter.
Egg whites
Whipped to stiff peaks, they lighten the batter and help the waffles rise and set.
All purpose flour
Forms the structure that holds the waffles together as they cook.
Baking powder
Releases gas in the batter, creating lift and a lighter crumb.
Butter
Adds fat for tenderness and rich flavor, and helps browning.
Light brown sugar
Adds sweetness and molasses flavor, and promotes browning on the waffle surface.

The step that matters

Folding in the egg whites. Whipped whites hold air that gives lift. Adding them all at once or stirring vigorously knocks out that air, leaving dense waffles. Fold gently, in portions.
