Honestly, people have been fermenting stuff safely for centuries without special gear. A clean jar and regular checking usually does the trick just fine. It feels like we sometimes overcomplicate perfectly simple kitchen tasks.
Lol that's so real. I read somewhere that most kitchen mold hides in places you never check, like under the fridge drip pan or inside the rubber seals of small appliances. The article said cleaning your fridge's condenser coils can actually cut down on mold spores floating around. Makes me want to go on a deep-clean spree.
