how's your yeast water?

Hi, friends.

I got a question from my friend about how it looks like when the yeast water is ready for bread baking.

The jar should look like this.
(please see the picture)

It looks like soda pop and has many tiny bubbles.(If yours look like this and still sitting on your counter, please move it to refrigerator.)

If you start making your yeast water more than 5 days ago and yours does not look like this( or anything close to this), add some sugar and shake your jar and wait for another day.

If you are using sulfured dried fruits, you might not get any good result...
