Hello and it sounds like you may have some issues here with your sourdough starter.
What should you do if you have "dead", "flat", or "barely living"
starter?
Begin the process of transforming it to a fresh, healthy
starter. I personally do not believe in throwing away "dead"
starter, since it typically can be revived from the few yeast and
lacto-bacilli that probably still exist. If restoring dead starter
takes longer than a week to see bubbles appearing in it (flat, barely
living or otherwise) then you've probably started a new starter from
local microorganisms. If so, and your starter was a special strain,
you'll probably want some of the original starter to start over with
rather than expecting this revived version to be the same as that
special starter. Remember that you have probably not really killed
your starter unless you subjected it to high temperatures for long
enough to thoroughly heat the starter above about 100F or so.
THE 1-TABLESPOON METHOD
1. Using 1 tablespoon of starter (discard unused portion or save a
little in the refrigerator in case of an emergency), 1 cup 75 degrees
water, and 1 1/2 cups all-purpose white flour, proof for exactly 24
hours at 72 to 77 degrees. It's very important to maintain these
precise temperatures and to proof for exactly 24 hours.
2. Examine the starter to determine what stage it's in. Assuming you
didn't overheat it, it should be "flat", "barely living", or
"healthy". Remember the clues to identifying non-healthy starter (low number of bubbles, early hooch, gelatinous consistency, no froth
on top, or any 2 or more of these symptoms. If your starter is
"healthy," you're done.
3. If your starter is not healthy yet, stir it well and refrigerate
it for no less than 12 hours.
4. Remove the starter from the refrigerator and go back to step 1.
This process needs to be repeated a few times ( usually around 4 or 5
times or so unless you were lucky. A lot of the home-dried starters
revive MUCH quicker than this.
Here's an alternative process you can use (possibly better, if the
above process doesn't seem to work well for you):
F. THE 1-CUP METHOD
1. Using 1 cup of starter, 1 cup of 85 degrees tap water (don't worry
about minerals or fluoride), and approximately 1 1/2 cups all-purpose
white flour, proof your starter for 12 hours at 85 degrees.
Maintenance of temperature is very important.
2. Examine the starter to determine what stage it is. Assuming you
didn't overheat it, it should be "flat", "barely living", or
"healthy." If your starter is "healthy," you're done. Remember the
clues to identifying non-healthy starter: low number of bubbles,
early hooch, gelatinous consistency, no froth on top, or any two or
more of these symptoms.
3. If your starter isn't healthy yet, stir it well and refrigerate it
for no less than 12 hours.
4. Remove the starter from the refrigerator and go to step 1). This
iterative process needs to be repeated a few times ( usually around 4
or 5 times or so unless you were lucky.
If the starter has not been used in more than 3 or 4 days, you may
wish to replenish the starter once (1 cup starter, 1 cup water, 1 1/2
cups flour, 12 hours at 85 degrees) to ensure the starter is really
fresh before preparing for a bread recipe. Most healthy starters are
fairly flexible, though.
Use the following table for amounts, and blend together the
starter, bread flour, and 80-85 degrees water. Measure the starter
and water carefully. The suggested amount of flour is only a
guideline. Blend enough in to make the starter the consistency of
mud (a little thicker than pancake batter):
Bread
Loaves Flour Water Starter
1 1 cup 1 cup 1 tablespoon
2 2 cups 2 cups 1 tablespoon + 1 tsp
3 3 cups 3 cups 2 tablespoons
Proof for exactly 24 hours at 72-77 degrees.
Concurrent to the above proof, replenish the original starter by
combining 1 tablespoon starter (discard most of the rest), 1 cup warm
water, and 1 1/2 cups all-purpose flour in another bowl or in the
starter container itself. Proof for 24 hours at 72-77 degrees.
Refrigerate the starter in the starter container.
Hope this helps and good luck
