In a medium bowl, mix together the starter, milk & flour. Cover it with plastic wrap & leave it on the counter overnight to rise.
Once hot, add about a 1/3 cup of batter to the hot skillet & let cook a few minutes until bubbles start forming on the top and it's golden brown on the bottom. Flip over & cook for another minute or so. (It will need less time on the second side.) Continue with the rest of the batter, being careful not to overcrowd the pan.
*If you don't have starter, here's a quick starter recipe I like.
*You can substitute whole wheat flour for the all-purpose flour.
*If you want to make these pancakes right away and skip the overnight fermentation, that's ok, just proceed with the recipe, combining the dry ingredients with the wet and cooking as suggested.
