Sourdough waffles

2 cup (454g) sourdough starter, unfed/discard
4 cups (908g) buttermilk
4 cups (480g) all purpose flour (or a mix of whole wheat and all-purpose)
4 tablespoons (56g) granulated sugar


4 large eggs
1/2 cup (100g) avocado oil or 7 tablespoons (114g) butter, melted
2 teaspoons baking soda
1.5 teaspoon table salt

In a large bowl, stir together the unfed starter, buttermilk, flour, and sugar.

Cover and let rest at cool room temperature (about 65°F to 70°F) for about 12 hours, or overnight.

To make the batter: In a small bowl or mixing cup, beat together the eggs and oil or butter. Add the egg mixture to the overnight sponge, stirring just to combine.

Add the baking soda and salt, stirring to combine. The batter will expand and may bubble a bit.

To cook the sourdough waffles: Pour the batter onto a preheated, greased waffle iron, and cook for about 2-2.5 mins (until steam diminishes). Repeat with the remaining batter.
