The night before you want to eat these pancakes for breakfast mix together the flours, sourdough starter and water. Cover with a lid and leave in a warm place overnight.
Your mixture from the night before should have bubbles on the surface and smell strongly of sourdough. Add the remaining ingredients and mix until just combined.
On a preheated griddle greased with butter ladle the batter, wait until the edges start to dry and bubbles come to the surface, flip and cook the other side until golden brown. Serve immediately for best results.
