Ingredients
460 grams (2 cups) lowfat buttermilk
113 grams (1/2 cup or 1 stick) butter, melted and cooled
100 grams (1/2 cup, stirred down) ripe sourdough starter
2 large eggs
55 grams water, used to thin the batter if needed
250 grams all-purpose flour
14 grams (2 teaspoons) sugar
5 grams (1 teaspoon) sea salt
3 grams (1/2 teaspoon) baking soda
Instructions
  1. In a large mixing bowl, add the flour, sugar (if making a savory waffle, omit this), sea salt, and baking soda. Whisk everything together.
  2. In a medium mixing bowl, add the buttermilk, melted and cooled butter, sourdough starter, and the eggs. Whisk everything together until homogenous.
  3. Preheat your waffle iron or waffle maker. If using a cast iron or aluminum waffle maker, be sure to lightly grease it with oil to ensure the waffles do not stick.
  4. Pour the wet ingredients into the bowl with the dry ingredients and whisk everything together until only a few small lumps remain (it’s OK if the mixture isn’t completely smooth). Use some of the reserved water to thin the batter if necessary; if you maintain a liquid starter you might not need any of the water. However, if you maintain a stiff starter or your flour is especially “thirsty,” add some water, a little at a time while mixing until the batter loosens up. In the end, it should pour from a spoon but not be runny or soupy, somewhere around loose honey rather than cold milk.
  5. Cook the batter in your hot waffle iron until done to your liking.
