My sisters and I got together for a canning day a few Sundays past. Forty pounds of tomatoes and a few dozen jars later, we have quite the larder of tomato bisque, whole tomatoes, and sauce. We were so excited about how this batch came out that we've got a more ambitious plan for August's canning session: pesto, roasted whole garlic, black bean soup.
It turned out to be easier than I anticipated, the canning. Aside from spending a large portion of the day preparing what needs to be canned and following the processing instructions for what you're canning (easily found), it's as simple as placing the cans in the double boiler for the required time, and letting them sit overnight once taken out. I recommend it to anyone who both laments the end of fresh veg season and has a little extra time on their hands on some too-humid-to-step-foot-outdoors August Sunday.

Looks who's cute! Madge is my sister's cat, and I got to spend some quality time willing myself not to pet her (she's a little skittish). I got a couple ear skritches in when she was very sleepy (don't tell her).
