To make the overnight sponge, stir down your sourdough starter and remove 1 cup (I put in 1 cup of flour and 4 oz. water to approximate sourdough starter).
2
In a large mixing bowl, stir together the 1 cup starter, flour, sugar, and buttermilk.
3
Cover and let rest at room temperature overnight.
4
In a small bowl or mixing cup, beat together the eggs, and oil. Add to the overnight sponge.
5
Add the salt and baking soda, stirring to combine. The batter will bubble.
6
Pour the batter onto your preheated, greased waffle iron, and bake accordng to manufacturer''s instructions.
7
Serve waffles immediately, to ensure crispness. Or hold in a warm oven until ready to serve.
