THE CONSERVO CANNER! All the way from 1929 and in my kitchen!
When visiting Whidby Island, Washington last month, we stopped in a little town museum where I came across a Conservo. We asked the volunteer manning the museum what it was. She said it was for canning and had belonged to the mother of one of the town residents. I HAD TO KNOW MORE. There isn't a great deal about the Conservo online, but I did find a pdf for the manual. I starting looking for one, found one on eBay and bought it. It is in mint condition. It was probably manufactured 1928-29 and looked like it had never been used. I have now used it to can apple grape juice (made with my steam juicer) and it worked PERFECTLY. I love it! The intro to the manual is in and of itself very interesting reading as it gives a lot of insight into what a family at that time (not a farm family) was eating and preserving.
The manual has recipes and times for canning every possible food. Obviously, these days we know not to can low acid foods in steam or water bath as they were doing then. You can find the manual here:
I called my County Extension. The food preservation expert knew of it but had never seen one. I'm going to take it in and show it to her. I'm attaching a pic of my wonderful Conservo in action. I'm going to use it again today to make Strawberry Rhubarb jam. It will hold 32 half pint jars and only takes up one burner on my stove! It's a real find. If you ever come across one, BUY IT!
