Replace Pickling Salt with Sea Salt in your pickling brine.
Sea Salt has more health benefits than processed salts. The concept behind pickling salt is that they are finely ground to allow them to completely dissolve into the brine. Accomplish this by purchasing a finely ground sea salt, or grinding your coarse salt with a mortar & pestle or electric spice grinder before use. An electric kitchen coffee grinder is great for grinding spices. Regardless of the salt and your method, simmer your brine until your salt is well dissolved.
For the brine, a solution of 5% salt is necessary if you are canning for shelf storage, you can decrease the salt if you are making refrigerator pickles. For shelf storage make sure you follow the necessary steps for proper home canning. I use the “USDA National Center for Home Food Preservation” site for all my home canning and freezing questions. http://nchfp.uga.edu/how/cucumber_pick.html
Here is a basic brine recipe:
12 cups water
4 cups white vinegar
2/3 cups pickling salt
Bring the brine to a rapid boil.
