I'm canning salsa now (water bath), but finished reading the directions for my pressure canner that I've had for over a year and haven't been brave enough to use. I don't know why, but I'm scared to use it. lol I have a huge 23 qt canner... better make use of it!
Now now don't be afraid. Just follow the directions and you'll be fine. NEVER, NEVER, NEVER leave things on the stove unattended. I used to have one but gave it to my niece years ago. Now I'm back into it and need a new one. Though this year the garden was a wash. Maybe next year.
I left a baby bottle on the stove and had to paint the ceiling. TWICE!! Milk sprayed out the nipple like a volcano. I'm thankful that's all I had to do.
