Unfortunately I'm in Colorado... Guava is not really common here. In fact I've never had any.
When
I was asked if it could be canned I did some research. I found
that Guava is really very healthy for you. For those of you who have
easy access to it here are directions for canning guava.
I have attempted to share safe preserving methods. However, I make no promises. You alone are responsible for your health. Be aware of current safety recommendations. See my Full Disclaimer Here
