Fill a jar with a 4 tablespoons of pink Himalayan salt.

Cover the salt with 1/2 cup filtered water, leaving some space at the top.

Seal and allow the mixture to sit for 12–24 hours so that the salt fully saturates the water.

You now have a “sole” (concentrated salt water). You can keep adding more salt or water as needed; the water is considered “fully saturated” when salt crystals remain undissolved at the bottom.
