Golden-brown sourdough waffles, infused with the tangy flavor of a well-fed starter, offer a delightful contrast of crispy exterior and airy, slightly chewy interior
Stir down your refrigerated starter, and remove 1 cup. Note: This is a good opportunity to feed the remainder, if necessary.
In a large bowl, stir together the 1 cup unfed starter, flour, sugar, and buttermilk. Cover and let rest at cool room temperature (about 65°F to 70°F) for about 12 hours, or overnight.
In a small bowl or mixing cup, beat together the eggs, and oil or butter.
Add to the overnight sponge, stirring just to combine.
Add the salt and baking soda, stirring to combine. The batter will expand and may bubble a bit.
Pour the batter onto your preheated, greased waffle iron, and bake according to the manufacturer's instructions.
Repeat with the remaining batter. Serve waffles immediately or hold in a warm oven until ready to serve.
