We are vacationing in Cabo San Lucas, Mexico and had dinner at a spectacular, elegant, and expensive restaurant last evening...El Farallon. They have a wonderful champagne bar where they offer a wide selection of French champagnes by the glass at rather high cost...starting at about $25 per flute. I was rather surprised to see 4 canisters of different exotic salts sitting on the champagne bar. I inquired and was told that they recommend putting a small pinch of salt in your mouth prior to sipping the champagne...that it enhances the taste of the champagne. I have never seen this before nor have I ever heard of such a thing. Is this something new that I'm not aware of?
