Who is the Saint for canning and preserving? June 28, 2016 by Addi 6 Comments I may need some prayers and good thoughts tonight. Who is the patron saint of canning and preserving? Saint Christopher? My first canning load of the season and the very first jar I put into the boiling water blew up in the hot water bath canner. I guess there’s one last jar of spicy rhubarb compote. Darn.
