For those curious as to what the recipe really said ... here is the link to the McCormick recipe for Dill Pickle Spears
. Obviously the recipe calls for a 1:1 ratio of water to vinegar - not the 3:1 Hopz posted which could affect the safety of the finished product - see ref here
which addresses the reduced vinegar question.
But - there is more than one way to make a pickle! Some commercial pickle makers add sugar (which is acidic) ... some completely ferment the pickles before canning ... some use the fresh-pack or quick process.
