canning or pickling cactus leaves (nopales)

A question from a reader… no answer for them. Anyone able to send us a canning and pickling recipe for nopales?
BTW, we also get requests for making jely from the fruit.

Hello -
Do you have a recipe for canning or pickling nopalitos for long-term storage?
I’m interested in a recipe that doesn’t require refrigeration.
Any help would be much appreciated. Thank you so much.
