My jar of whole wheat sourdough starter was full and it was time to either use or discard some of it. I made crepes using mostly sourdough starter, a little all purpose flour, an egg, olive oil, salt and water.
For the filling I sautéed onion, jalapeño and mushrooms in olive oil before adding chopped fresh spinach.
I then added chopped Brie, thyme, tarragon and chervil. (Should have left out the tarragon and maybe used a little nutmeg instead).
Since the crepes were made largely of sourdough starter they were notably sour. I thought they tasted good that way.
