I found this video https://www.youtube.com/watch?v=K0NH2NSiUbA on youtube, so I looked around fillmore container and found these woozy's http://www.fillmorecontainer.com/5oz-Woozy-Hot-Sauce-Bottles-Wider-Mouth-P368.aspx from Fillmore container with the continuous thread plastisol-lined caps suitable for hot packing. Has anyone used these? any opinions? To me it seems pretty straight forward and at the end of video shows how to tell if the lids have sealed.
