Equipment:

• LARGE MOUTH mason jars. https://www.amazon.com/dp/B07YNGK6XJ
  • You want large mouth just so that they fit the fermentation weights. You can get smaller jars if you want.
• Gas relief valves. https://www.amazon.com/dp/B01LWS63OF is what I have, but you can get whatever.
  • This is so that you don't have to baby sit the jars and 'burp' them daily (otherwise they'll explode).
• Fermentation weights. https://www.amazon.com/dp/B076V66FZ4
  • These make like so much easier. They just sit on top of everything in the jar, preventing anything from floating to the top, which you want to do because if they are exposed to air they can get moldy and ruin your whole ferment.
• Hot sauce bottles. https://www.amazon.com/dp/B0CQ832R6B?th=1
  • Or anything you want to put the hot sauce in. These are the typical hot sauce bottles.
• pH tester. I just got cheap strips. https://www.amazon.com/dp/B0811PYS6T
