Decided
to do an internet search on natural yeast and went to the National
library to borrow books on natural yeast bread. I found out that this
kind of bread making is not only prevalent in Europe but also in Japan
and Taiwan (in this case, in recent years) and is very much gaining
popularity around the world again due to its health benefits, in
particular, the lactic acid in the sourdough and bulk fermentation
process breaks the phytic acid in the grains and wheat and allows the
nutrients from the these grains to be better absorbed by the body.
After doing all my readings and watching the videos, I decided to take a plunge do the sourdough levain in two stages:
Stage 1 : Grow my Yeast Water
Stage 2 : Grow the Starter
Stage 1 Growing Yeast Water
It seemed all so easy from the readings.
(1) Need some fruits with yeast
(2) Water and sugar (optional)
(3) Sterilized clean bottle.
However,
I did fail twice before I could get my yeast water to produce the
starter. Read my 2 failed attempts below and finally my final success.
Attempt #1 (Failed attempt)
 |
| My first failed attempt at raisin yeast water. |
1st Day : Added fruits to water and sterilized clean bottles.
I
first tried with organic raisins (without oil! I did read the label)
and organic apples. But only with filtered tap water (using a Brita
filter).
3rd Day :
There
were some bubbles on the third day for my apple yeast water but none
for my raisin. Don't know why because many books said that it was
easier to get yeast water (and the bubbles) from raisin. Went to check
my raisin package again - yes, it does says organic and there is no
line, no passage of any oil anywhere on the package.
I decided to transfer some apple yeast water on my raisin.
4th Day:
Finally
saw some bubbles in the raisin yeast water! Was it because of the
apple yeast water or raisin yeast water? Not sure. This is bad, I am a
physicist ..... changing two variables at one time (time and adding of
water from apple) does not allow me to find out which is the cause of
the bubbles.....too impatient. Hm....but I did start to see some white
bits floating on the apple and raisin.
5th Day:
Saw more bubbles....in both bottles, very, very happy! Decided to take some out to make the starter.
Did
a starter for both raisin water and apple water. 50g starter water, 50
g flour, 1/2 tsp of sugar to get it going. It did double after 12
hours.
6th Day:
I
fed it some more now 100 g flour and 100 g water. It continued to
double after 12 hours. I didn't understand why I must discard, seeing
that there my bottle was not filled I decided that I shall not discard.
7th Day:
I
thought the starter was stable, some books and website did say you can
make a starter dough immediately after having the bubbles. So I did and
tried to bake with it. Made the dough in the morning. However, even
after 6 hours of wait, the dough did not rise at all. Was so
disappointed. Threw away both the starter water for both the raisin and
apple, the (what I thought was) levain and dough of the bread. Ending
my journey for my first experience of yeast water making.
Attempt #2 (Failed attempt - or an attempt which could have succeeded but I would never have known)
 |
| My second attempt at yeast water with apple. |
I was convinced that I couldn't fail, if others have done it before I should be able to do it. I went back to the books and searched the internet, reading article after article.
"Maybe it was the water?" Many people find success with mineral bottled water. Maybe our water is too chlorinated.
To spur me on, Tze Wei decided to get me a bottle of Evian water.
This time I decided to change the water to Evian water and decided to have sufficient fruit to ensure there is sufficient sugar to feed the yeast.
So the second attempt goes like this:
300 g cut apples
200 g Evian Water
1 tbsp of organic sugar.
Day 2 -3 : I got bubbles from day 2-3 and it did look promising.
Day 4: The water still smells good and bubbles are still there.
Day 5 : HORRORS! The bubbles disappeared! No more?!!! Why??? Why??? The water got cloudy.....no signs of life :< By evening I still saw no bubbles :< upset, upset. Am I wasting my money and time? Urgghhhh maybe I should give up. Threw away this bottle of yeast water.
Alas, the end of experiment 2.
Attempt #3 (Final Success- or an attempt which could have succeeded but I would never have known)
I didn't quite dare to try after my first 2 failed attempts. Was angry and frustrated because it is not very cheap and easy to get organic fruits in Singapore and the stuff don't come cheap. I was actually wondering if it was all worth the effort then.
Again, my sweet, sweet husband nudged me on again.
"There is still the Evian water left? Don't waste it. Don't you always encourage your students not to give up and keep trying. At least do one more experiment and use up the water."
He even drove me down to the nearest Finest NTUC to hunt for organic grapes. His theory- maybe the apples were irradiated before imported in, let's look for fruits with obvious yeast on the skin.
So we went down to the supermarket and lo and behold, there were organic grapes (we don't always have them). Choose a small box with the most cloudy skinned grapes and went back to start my 3rd experiment.
1st Day :
200 g organic grapes (halved)
300 g water (Evian)
1 tsp of organic sugar
1 sterilised glass jar.
This time I used a double folded cheese cloth to cover my bottle, and just lightly twist in the cap. Read somewhere that the yeast needs to breathe! So I should not have been sealing up my bottles cos I would have deprived all my yeast of the oxygen if there were any. Instead of giving it a swirl, I was advised to keep give it a vigorous shake, which I did.
2nd - 4th Day: Small bubbles emerged on the 3rd day, just as before but I didn't dare to get my hopes up too hig.
5th Day: By the 5th day however, the bubbles disappeared again. I was disappointed, but decided to just keep feeding. Didn't quite like the smell, the apple yeast water was definitely better smelling. The only difference was I decided to not throw this time. Some books say keep for 7 days and I decided to do so. Gave it a shake in the morning and another time at night.
6th Day: No bubbles still. But did not want to give up and persevere I shall. Isn't this what I always tell my kids and students to do? Anyway no harm and no mould is growing, so why don't I just continue.
7th Day: Finally! I wokeup this morning and there were big bubbles, really big ones, and I could see effervescent, like soda pop. The earlier acetone smell was gone and it was definitely like alcohol sweetness. Putting my ears at the opening of the bottle I could definitely hear the bubbles popping. Fizz Fizz....SUCCESS Finally.
