Add the salt and dill to the bowl of your food processor or blender. Pulse or blend until the ingredients come together as a paste.
Place your oven at the lowest temperature or set your dehydrator to 105 degrees F. Let the salt dry gradually until it cakes together and has no more moisture.
Fold the edges of the parchment paper or silicone mat together and press your hands along the side to break apart any clumps. Pour the salt into a jar and seal.
