make and maintain your own sourdough starter
you can make your own.
you'll need a volume of at least 1 and 1/3 cups.
there are several ingredient combinations for making wild
1 is to grate a raw potato. then add enough water to cover
another method is to use water that you've boiled potatoes
pancake consistency batter.
yet another is to simply mix together equal amounts of water
anything that provides food for the yeast and a good growing
environment will work. yeast needs sugar or carbohydrates
(which it converts to sugar), and clear liquid.
make your choice based on what you have handy and just because
that's what you'd like to try. don'tsp worry about whether or
not 1 set of ingredients will work better than another
because the chances are that they will all be equally
efficient in attracting wild (sour) yeast. there is no exact
recipe because there are so many other variables in each house
that will invite or dissuade wild yeasts from entering the
mixture. if at first you don'tsp succeed, try, try again. the
most important thing is the method.
when you have decided on the ingredients you want, put them in
a glass container that will hold at least three times the
volume of the ingredients. mix lightly with a wooden or
plastic spoon as some metals will react to it. the working of
the starter will mix itself.
leave the mixture undisturbed and loosely covered with a cloth
or perforated plastic (to allow gases to escape) at warm room
temperature until it begins to froth or work and expand.
this is a sign that wild yeasts have made themselves at home
and that's what you're after. the new starter will rise up in
the container, then fall again. when it has, it's ready for
use. (note: it will smell sour!)
when you use it, always leave some in the container and add
you will probably see a liquid covering the top at 1 time or
another. this is called hooch, and it's exactly what it
sounds like , but don'tsp drink it! actually, it's harmless, so
about either way.
keep sourdough in the refrigerator unless you use it at least
every third day. if you use it that often, you can leave it on
the counter or any place where it's safe. if you can'tsp
refrigerate it, you can keep it fresh by throwing out a cup of
it every second or third day and then replenish with flour and
water. wait until it works again before counting days.
a properly cared for starter can live indefinitely, but if you
literally suffocate in its own waste products. if the starter
baking powder recipes. simply put, you substitute sourdough
for leavening and part or all of the liquid.
