Tie the sage, bay leaves, and thyme together with butcher’s twine, or bundle them in a piece of cheesecloth tied closed with twine. Place the herb bundle in the saucepan, along with the water (or water and broth) and the measured salt. Bring to a boil over high heat, reduce the heat to low, and simmer gently for 30 minutes. Discard the herb bundle, keeping the broth at a simmer.
