Sourdough Waffles

This recipe requires your sourdough starter to be fed on a 12-hour schedule. If you usually refresh every 24 hours, simply begin feeding your starter every 12 hours two days in advance. Once you reach the fourth feeding, you can start making waffles from your discard. Similarly, if you typically keep your starter in the fridge, bring it to room temperature and feed every 12 hours for 3 days before waffling up.

Ingredients

125 grams discarded Sourdough Starter (unfed), recipe follows

1 cup whole milk 

170 grams unbleached, all-purpose flour 

1 large egg, separated 

4 tablespoons unsalted butter, melted and cooled 

1 tablespoon granulated sugar 

1 teaspoon kosher salt 

1/4 teaspoon cream of tartar 

Nonstick spray

To Begin:

125 grams all-purpose, unbleached flour

125 grams filtered water, room temperature 

For Daily Feeding:

100 grams all-purpose, unbleached flour

100 grams filtered water, room temperature 

Directions

Special equipment:
scale with tare function; quart-sized, wide-mouthed glass jars with lids; hand mixer; Belgian waffle iron
  1. Combine the starter, milk and flour in a medium bowl and cover with plastic wrap. Rest for 8 hours at room temperature, until the batter is light, full of bubbles, and roughly doubled in size. (If you'd like to make these for breakfast, you can refrigerate the batter overnight after this 8-hour rest.)
  2. Stir the egg yolk, butter, sugar and salt into the starter mixture until just combined and set aside.
  3. Beat the egg white and cream of tartar with a hand mixer on high until stiff peaks form, about 1 to 2 minutes, then fold the egg white into the batter using as few folds as possible to keep it from deflating (see Cook's Note). Rest the batter at room temperature for 20 minutes.
  4. Heat a Belgian waffle iron on medium heat. When hot, lightly coat both plates with nonstick spray. Ladle the recommended amount of waffle batter onto the iron according to the manufacturer's recommendations and cook until crisp and golden brown. Serve immediately or cool on a rack and wrap in plastic wrap followed by foil and freeze for up to 3 months.

For Daily Feeding:

  1. To begin: Mix together 125 grams flour and 125 grams water with a clean hand in a medium glass bowl. Cover the bowl with a tea towel and let sit undisturbed at room temperature until the mixture is full of bubbles and has nearly doubled in size, usually 2 to 3 days. During this time, yeasts and bacteria from the air and from the flour and probably from you will set up housekeeping in the bowl (see Cook's Note).
  2. For daily feeding: Peel back any crust that may have formed and transfer 20% of the culture (50 grams) to a clean, wide-mouthed jar. Stir in 100 grams flour and 100 grams water, loosely screw on the lid and stash at room temperature for 24 hours. (The culture will have a stinky-sour smell at this point.) Discard the rest of the original mixture.
  3. Repeat step 2 every 24 hours for 5 days. By then the culture should smell yeasty-sweet-sour, which means you're ready to put the starter to work. The waffles are to be made with the discarded percentage of starter.

Cook’s Note

If your culture isn't showing signs of life after 3 days, go ahead and start feeding. If, after a few more days, nothing happens, start over and place the culture in a different part of your home. We're not saying a stand mixer wouldn't work, but given the volume, an electric hand mixer is easier. If you don't have one, you can certainly use a hand whisk, but it's going to take some elbow grease and a couple minutes more to reach stiff peaks.
