Feed sourdough starter 4-12 hours before whipping up this recipe.
Preheat cast iron waffle maker or a plug-in waffle maker.
In a large bowl, mix together fed sourdough starter, eggs, oil, and salt.
Sprinkle baking soda over batter and stir well.
Add shredded cheese.
Grease the waffle maker and add the amount of batter suggested by the manufacturer. (Mine takes about one cup of batter.) Close the lid.
If using a cast iron waffle maker, cook the waffles for 4 minutes on one side and flip and cook another 4-5 minutes on the other side. If using a standard, plug-in waffle maker, cook for about 7-8 minutes.
Open it. If it is sticking at all or seems uncooked, cook for another minute or two and try again.
Notes
This recipe utilizes fed/active sourdough starter. This is sourdough starter that has been fed 4-12 hours before starting this recipe. It should be nice and bubbly.
These taste best when they are really crispy and the sides are golden.
If using melted coconut oil for this recipe, make sure to allow it to cool a bit before pouring into the eggs and starter. This will prevent it from cooking the eggs or killing the beneficial yeasts in the starter.
