Onions

To preserve onions, you want to wash and peel the onions then put them in a medium-sized pot of water. Let the onions boil for seven minutes and then remove them from the hot water. Then add a few teaspoons each of salt, ground ginger and black pepper to the canning jars before putting the onions in them. Fill the jars with the hot water and seal them. Finally, place the canning jars in a pressure canner or 30 minutes.
