What do I do with 1 tbsp of leaven
so glad I found this site as my journey with sourdough begins. I was given 1 tbsp of leaven to start my sourdough bread making. I just fed it enough for one loaf. I have saved a tblsp or so to go into the refrigerator until my next batch of bread. Do I have to feed it prior to putting this small amount in the refrigerator? I have read many articles but I was unsure.
