Asparagus

Asparagus

To preserve the asparagus, you want to wash the asparagus and cut off the spears. After this step, you would trim the asparagus so that it is at least five inches. Then take a large canning jar and place the asparagus inside it. Then add some diced onions, a few teaspoons of salt, and hot water to the canning jar. Place the canning jar in a canner so you can pressure the asparagus.
