Smart eBay searches we'd start with ourselves. We earn a small commission on qualifying sales through these links, and 90% of it goes to charity (you can pick which); the price you pay is the same whether you use them or go direct to eBay. Full disclosure.
Wide-mouth mason jarsHalf-gallon wide-mouths are the workhorse vessel for everything from sauerkraut to kimchi to hot sauce.
