Tonight, around 9pm, I checked my spreadsheet and notebook and tried to remember what I did last time. I came up with this list of ingredients:

• flour
• water
• poolish – 210g
• salt
• yeast

Then I put a plastic container on the kitchen scale, hit the tare button and added about 1/8tsp of yeast. It didn’t even register as a gram. Then I added 105g flour and 105g filtered water. I covered the container and let it sit on the counter for about 30 minutes. Then I stuck it in the fridge and went to bed.
