Notes
Optional Add-ins: Mix in chocolate chips, blueberries, or other favorites before pouring the batter into your waffle iron.
Adjust the Recipe: Scale the recipe up or down in 250g increments depending on how much discard you have.
Freezing Tip: Freeze the waffles in freezer-safe
Egg Substitute: Another baker has an egg allergy and substituted flax eggs for the eggs and said they turned out amazing! A flax egg is 1 tbsp ground golden flaxseeds mixed with 3 tbsp warm water.
