In A Pickle Pickling

You are making pickles and after you open the jar you notice that the pickles don't look quite right.

Here are a few results that you might find and the cause of them:

The Pickles are Hollow
Your cucumbers may not have been fresh or they were poorly developed when you started.

The Pickles Look Shriveled
When this happens, your solution may have been too strong. (salt, sugar or vinegar)

The Pickles are Soft or Slippery
Your solution may have had too little salt or vinegar. It is also possible that you got an imperfect seal or you did not process them long enough. In this case discard the pickles and try again.
