One resource that's been super helpful for me is https://justcanning.com/ . They have a ton of tips and tricks for safe and successful canning. It's crazy to think that something as simple as a jar of food could be so dangerous if not done right.
I've since updated my canning practices and feel...
I learned this the hard way when I first started canning. I was following some old family recipes, but luckily, I stumbled upon some modern canning guides that emphasized safety.
