Classic Sourdough Pancakes or Waffles
from https://www.kingarthurbaking.com/

With their mild tang, sourdough pancakes are a tasty change from your usual breakfast short stack. You might worry that their flavor will be strong enough to clash with syrup or your other favorite toppings, but no worries: pancakes made with sourdough starter simply taste a bit richer and more nuanced than the norm. And sourdough waffles? They're perfect for either a drizzle of maple or as the base for savory toppings like fried chicken.

We make just half the recipe for the two of us and it is plenty. I thought the pancakes could have baked up a little thicker the first time we made them and we added another tablespoon of flour the next time. This worked better. Also, if we are having pancakes for dinner, we make the sponge early in the day.

Overnight sponge:

2 cups (241g) King Arthur Unbleached All-Purpose Flour
2 tablespoons (28g) sugar
2 cups (454g) buttermilk
1 cup (227g) sourdough starter, unfed/discard

Waffle or pancake batter:

all of the overnight sponge
2 large eggs
1/4 cup (50g) vegetable oil or 4 tablespoons (57g) butter, melted
3/4 teaspoon salt
1 teaspoon baking soda

To make the overnight sponge: Stir down your refrigerated starter, and remove 1 cup (227g). Note: This is a good opportunity to feed the remainder, if necessary.

In a large mixing bowl, stir together the 1 cup (227g) unfed starter, flour, sugar, and buttermilk. [Stir only until flour is mixed in so that gluten does not form.]

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 to the overnight sponge.

Add the salt and baking soda, stirring to combine. The batter will bubble.

To make pancakes: Pour the batter by the 1/4-cupful onto a preheated, lightly greased griddle. Cook until bubbles form and pop on the top side of the pancakes, then turn over and cook until browned underneath.

To make waffles: Pour the batter onto your preheated, greased waffle iron, and bake according to the manufacturer's instructions. Repeat with the remaining batter.

Serve pancakes or waffles immediately, with your favorite toppings; or hold in a warm oven until ready to serve.

Storage instructions: Store any leftovers in the refrigerator for a day or two; freeze for longer storage.

YIELD about 2 dozen medium pancakes or 1 dozen 8" waffles
