Homemade Yeast starts from an Apple


During the recent Japan trip, i visited a bookstore even i don't know Japanese, and also bought a book title with "Homemade apple yeast" . I have been thinking to making my own yeast, so this is my 1st homemade yeast from an apple..

I thought with the step by step photo shown in the book and i know Chinese letters, i should draftly know how to make this apple yeast..After went through the book, I still have few points that not so clear on how to do it. Luckily i found Yee's corner who know Japanese language, so she helped me to translate all these recipes. Thank you very much to Yee!!

Tomorrow i will share with you the 1st bread that i made using this apple yeast


Making Apple Yeast Extract
(recipe source: adapted from a Japanese cookbook, translation done by Yee's corner)

Apple half (whichever type of apple is ok)
Fine Sugar 10g ( i use organic sugar)
Water an amount that can fill up the container ( I use mineral water)
a container about 500ml

How to make:-

1. Wash the apple, remove the core, retain the apple skin, then slice and cut into cube size.
2. To sterilize the container -to fully soak & sterilize all the container and its lid & other parts (if any )into the boiling water for about 3 mins; after sterilised don't wipe it to dry but leave it dry naturally .
3. Put all ingredients and cover with the lid, shake the container and let them mix well, put in a shady place where temperature around 20C to 30C for a week to 10days. To prevent the apple be dry up, shake the container once a day.
4. During 5 to 7days, bubble will be formed. Once a day open the lid and let the gas released (go off) from the container.
5. Other 2 days somehow the white and muddy water becomes thicker, there will more gas released out, open the lid and when you hear “bond” sound and it means the fermentation is done.

**to have a good standard of extract is you have smelt that kind of fruity and yogurt “stink” at the end of the fermentation.

Next we are going to use apple extract to make yeast. Once a day we use bread flour and water as a base to continue feeding/ growing the yeast. Let’s enjoy the joy of feeding and growing the yeast.

1st Day

Bread flour 100g
Apple Yeast extract 60g
Airtight container about 1.6L

1. Weigh a 60g apple yeast extract.

* the remaining apple yeast extract can be stored in fridge for use in case failure.

2. In a bowl, pour bread floor and apple yeast extract, mix it well with rubble spatula or hand.

*Kneading is not necessary here.

3. After forming into a soft ball, transfer it to the prepared container, cover with the lid and leave the container in a place where the temperature about 30C for 2 hours to half day .

4. Let the yeast relax, when it rise to a double size, cover back the lid and store it the fridge.


2nd Day

Bread flour 80g
Water 48g

1. Take the yeast from the fridge, pour the yeast into a bowl and add in all bread flour and water, mix well with a rubble spatula or hand.

• kneading is not necessary, only mix till the flour incorporated well.

2. Put the yeast back to the container (the container to be washed) and cover with the lid and leave the container in a place where the temperature about 30C for 2 hours to half day .

3. Let the yeast relax, when it rise to a double size, cover back the lid and store it the fridge.

Day 3 to Day 5
Repeat the same procedure as day 2.

Day 6

The fermentation is completed, the degree of fermentation is getting strong as you keep mixing the yeast, in 6th day the container will be full of yeast and the fermentation process is done and completed. You can use it to make bread.

About Storing and Keeping the yeast-keep it in the fridge

This is the Japanese book that I bought..fyi..

Honey Bee Sweets said...

You know I did once with raisins and it failed. I was contemplating whether I should try it again. Looking at your apple yeast sure makes me want to try again....:)

蓝色小厨 said...

Faeez said...

Oooo.... this is interesting... Can't wait to read abt your bread using this home-made yeast:)

Sem said...

You are so lucky to hit it right the first time. I have bought the natural yeast recipe book from Taiwan, and had tried three times making the raisin yeast but failed miserably, wasted my precious raisins >.<
I also recalled seeing yeast made from yoghurt, maybe it is better idea to try apple, must be red apple?

鲸鱼蓝蓝蓝 said...

厉害哟
我也想自己养酵母
不过一直没有行动
哈哈

eileenlee said...

蚊子 said...

Sonia ~ Nasi Lemak Lover said...

Sem, in the book said any type of apple is ok..but i think don't use green apple which is sour.

joceline lyn said...

很厉害leh。。。。。。之前我妈咪就做了黄梨天然酵母。有时间和耐心去处理其实是很好的。起码是天然、健康的。

アンゼエリン said...

Ya I've heard of making yeast from Apple.

sweetsamsations said...

Never knew this was even possible!! Super excited to see how your bread turns out!! :D

Hi

I've tried apple and raisins with success.. If you are lazy to go all the way ( feeding the apple extracts with flour and water), you can just use the apple/raisins extract in place of water in any of your recipe. Especially those raisin bread recipe. And use instant yeast as per normal. The result is a very fragrant loaf of bread.

Good job Sonia... Can't wait to see your bread.

Regards
Chris

mui mui said...

Hi Sonia,
I also have tried to homemade my own natural yeast. I use dried longan, the result is good, I can say. Yesterday, I have baked my first batch of wholemeal bacon buns.
I get to learn this from Carol Hu's book.
Your homemade apple yeast looks great..looking forward to see your homemade yeast bread..: )

WendyinKK @ Table for 2..... or more said...

Interesting .... Wah, u keep us suspense over the bread. Can't wait can't wait!

Sally said...

天然酵母面包真的很不一样,味道很香。。
我是懒惰人,只做过一次苹果酵母而已哈哈哈。。。

Janetan said...

hi sonia,
the yeast making process just like the sourdough making too..
i wonder if your coming bread will be sour or not.. hope to see your bread soon..(i use this method to make bread too. and the result of the taste is quite sour but my son love it)

Angelic Heart~ said...

This is very interesting! I have had made once before with different method, the outcome is not nice. maybe i should try your method. THX Sonia!:)

busygran said...

Looking forward to your first bread with your first yeast!

Karen said...

Wow.. you are great sonia, but i still prefer instant yeast, more easy leh.. haha.. thx for sharing.. :)

Jeannie Tay said...

Very interesting, similar to making wine!

Anya said...

Wow! That is the first time I see that it´s possible to make yeast at home. I would love to try it! Just one little question (maybe it appears in the book). If I don´t want to use the extract in the same bread, how do I store it?
Love your blog! You are doing an amazing job there!

lena said...

interesting, not sure if i hv the patience like you to make this...hehe..

Nami | Just One Cookbook said...

How interesting!!! I've heard about apple yeast from my friends, but never read about it or seen making it. It was fun observing how yeast is made, Sonia! I wish I can eat your bread... :-)

Caca said...

Stephanie said...

Glad I found your blog! I have a question, though... I bake gluten-free bread. Do you know if I can feed the yeast gluten-free flour (i.e. Brown rice flour or sorghum flour), or does yeast need to feed on glutinous flour? Thank you!
