I will find some suitable container.
One thing I’ve saved a lot of is the plastic jars that Dole fruit comes in. They’re canned that way and those jars are great.
Mr. mm has insisted on saving them because he said the plastic used in processing fruit to have a longer shelf life like that has to have oxygen barriers in it. And they don’t break if the fall off the shelf, the ONE HUGE drawback to regular canning jars.
