Oh, Jordan, they have real good pickle brine mix at Wally. I think it's Mrs. Fields or Ball. The instructions are right on the bag, it's idiot proof. Real good pickles, too. You can add garlic and hot peppers or sweet peppers to kick it up a notch. Super easy.
The most important thing is to make sure the rim of the jar is clean and everything is good and hot when you put your lid on.
