Sourdough - bought a 150ml 'mother'... What next?
I am a crumpet maker in London trying to diversify my range and offer sourdough which I have never worked with before.
Today I received a 150ml container of sourdough mother. There were limited instructions on the container starting to feed it with an additional 150g of flour (type unspecified), and 150ml water (temperature unspecified).
I weighed up the amounts - I used Strong White bread flour which is what I have available, and cold water. I emptied the mother from it's small container into a tall Kilner jar (Mason jar) and added the flour and water. It was difficult to mix due to the restricted mixing room withing the jar (perhaps I should have done this in a bowl first then emptied the resulting batter into the jar). Consistency looked ok.
It is now sealed and standing at room temperature.
My main concerns now are whether or not I have ruined the starter already by using cold water? I read after that warm water was needed...
Please let me know your thoughts and any advice on how often to feed and what quantities to use would be much appreciated! Also, when would I be able to begin using the starter and is the amount I feed equal to the amount used?
