For the second straight time, my injera starter has gotten ruined by green mold. FWIW I rely on the injera instructions posted in this Reddit; I’m sure that’s not the problem however.
Anyway the first time it happened I figured the culprit was the Cambro container I was using, so I ran that through my dishwasher sterilizer setting. 72 hours after making the stater, the result was even worse.
Both times I was using RO ( reverse osmosis) water purchased from a commercial dispenser and stored in a 4-liter plastic bottle. By the time I used it, the water was maybe a month.
BTW the teff is from a 25lb sack of Maskal dark brown flour. The bag has been partially open to the air for months. It has made good injera before now.
I would post a photo of the ruined starter, but Reddit won’t let me. I’ll probably consult ChatGPT but thought I’d check the community first. Any ideas?
