I'm new to the forum. I have been baking "normal" bread for a few months from 2 Paul Hollywood books.
I'm following this recipe http://www.bbc.co.uk/food/recipes/sourdough_starter_with_45126
I started my culture 2 evenings ago in an airtight kilner jar and the culture is now nearly filling the jar and really frothy. I'm not sure what to do with it as another day to go and worried it may explode or something! Do I rehome and continue waiting another day or could it be ready for the next step? This morning it was halfway up the jar with the odd bubble. I'm not sure if I will contaminate it opening the jar for too long.
It is hot for the UK. Normally my cultures/breads don't rise that much.
