Combine the apple cider vinegar, sugar and kosher salt together in a saucepan. Bring to a boil, stirring until the sugar and salt dissolve. Remove from the heat and add in 3 ½ cups of water. Let cool 15-20 minutes.
Layer dill, ginger, pickling spice and crushed red pepper into the bottom of each mason jar. Then layer the pickle spices into the jar.
Pour the cooled water mixture on top, making sure the pickles are covered.
Seal and refrigerate for a few days before eating.
