After I posted Episode 11 about Wartime Canning, this original form that I ordered came in mail! It's an application for home-canning sugar allowance. One interesting thing to note is that while the form has not been filled out, the required rations stamps have already been affixed to the form! This got me really excited!

This jar is missing its separate rubber ring.
1. Why we shouldn't we use vintage canning recipes? Vintage canning recipes shouldn't be used for safety and quality reasons. Since WWII, a lot has changed with home food preservation, from the food science we now know and understand, to the canning equipment home canners use, as well as changes in the ingredients. Home canning equipment has improved with evolving science and technology over time. For example, we use a 2-piece metal lid to have a stronger vacuum seal, versus the 1-piece metal canning lids. Improved knowledge about home canning, improved home canning equipment, and improved knowledge about changes in produce (think of all the new variety of tomatoes since WWII), have made home canning practices safer for all. We would say that recipes prior to 1997 could be considered "vintage" because of the new information and equipment surrounding home canning.
