A better way to make salt
Sensing that we had room for improvement in our salt-making efforts, we sent a sample of our salt to Mark Bitterman, author of the recently published Salted and the “selmelier” at The Meadow in Portland, OR. He seemed generally impressed that we had made our own salt with water straight from our local patch of ocean. However, he did mention right off the bat that our salt was “really high in aluminum, probably from the baking trays that are being used.” I had suspected that the slightly gray color was from the trays, and now I knew for certain.
Mark suggested we use glass or Pyrex for baking the brine, since both are inert materials. I’m actually a bit embarrassed that I didn’t think of this myself.
