Rose (I feel as though I know you since reading your book since Christmas),
In making our own starter we followed the directions day by day, my wife and I are both engineers so lists and organized plans are VERY helpful. The starter didn't appear to follow the double a day that you mentioned. This may have happened while we weren't looking and then deflated. At the 5 day point, we decided to keep with the daily routine. At the 10th day, the starter does look a bit more energetic.
Do we need to mature the starter by feeding it every 3 days at room temperature or should it be in the fridge? How much should we be feeding, 60g of flour and water without removing any while it is matured? Should we remove a cup before we start expanding it?
We would both appreciate even a quick response. The description that starts at the end of page 429 "for example ......" confuses us when we follow the instructions in the last paragraph of page 433.
Thank you in advance for the help,
because sour dough is an alive entity it is not something the you can nail down hundred percent.
The last paragraph on page 429 of my book referred to an already established starter. The last paragraph on page 433 is referring to one that is not yet mature.if you have an active starter as I mentioned at the bottom of page 433 if you don't plan to use it for several days feed it to double it, let it sit one hour, and then refrigerate it.
as I wrote, for the first two weeks feed it at least three times a week.if you are not feeding it every day you need to refrigerate it between feedings. I wrote that during maturing you need to keep a minimum of 1 cup. In answer to your question how much to feed it, I wrote that you need to at least double it, so this depends on how much you keep. You can do it by a eye, or as I prefer, by weight.
By way of encouragement, everyone who has written to me about problems starting a sourdough starter has, with patience, arrived at a successful one. What follows is one person's very helpful suggestion which I have not tried myself but suspect will work brilliantly:
"... i had a asked for advice earlier about a sourdough culture that was
going flat and not responding to the feeding after 2 days. the trick i had
about using a 50/50 mix of organic rye and bread flour during the next
feeding to reintroduce more wild yeast into the sourdough did the trick of
waking it back up. it responded right away and i just went back to normal
bread flour feedings. i haven't had any troubles since in case anyone in
the future has this problem"
