Pour lemon juice into a small pitcher or container with a spout. Add sugar to the juice and stir with a long spoon until the sugar dissolves completely. It's best to do this at room temperature since sugar dissolves more slowly in cold liquids.
Pour dill pickle juice into the same pitcher, then add water. Stir the mixture for about twenty seconds until the color becomes pale and even. Taste it here and adjust the sugar or pickle juice to your liking before moving on.
Fill each glass with ice, then pour the lemonade on top. Add a small dill pickle and a lemon slice to each glass for a nice touch that hints at the flavor. Serve immediately for the coldest, most refreshing sip.
