How to make homemade yeast water from pear

Day 1: Mix all ingredients and leave warm place.

Day 2 or 3 (sometimes it takes more than 5 days): The bubbles shows up! It's fermenting.

Open lid and shake it. And close lid again. (You need to do every day.)

Day 3 or 4 (sometimes it takes more than 1 week): Stop to forming, and sweet alcohol smell. It's mean the yeast water is ready.

Strain the yeast water, and put back it into container.

Put it in the fridge to rest.
