McClure's pickles are the choice of this household, the garlic/dill ones. When the jar is empty and only the brine remains, I pour the juice into some of these molds.
We like them as is. Savory popsicle.
Pickle juice is believed to be a very good rehydrating solution and we live in an area of high, dry heat. I've even used this frozen brine as ice cubes in plain tomato juice with a shot of hot sauce and Worcester to make a Virgin Mary.
