Letting potatoes cook in the pickle juice and water solution will infuse them with all the herbs and flavors from the pickle brine, long before they are even part of a dish.
This tasty trick works on all kinds of potatoes. Just be sure to peel or cut your potatoes, or use potatoes with thin skin so the pickle juice can permeate the flesh of the spud.
Once your potatoes are fork-tender, just drain them, and from there you can pan-fry them to a golden crust, now that they are already tender in the middle.
