Saddle Rock is one of New York’s famous old oyster names, and another great example of an oyster craze. The original Saddle Rock was a formation in the East River near Norwalk Harbor. There, in 1827, exceptionally large and tasty oysters were discovered. Saddle Rocks quickly became all the rage, known especially for their prodigious size. If you liked large oysters, you looked for Saddle Rocks. By 1832 Saddle Rocks were kaput, but that was no problem for enterprising New Yorkers, who by then sold any large oyster as a Saddle Rock. The name faded away, though memory of it did not, and now it has cleverly been revived—and trademarked. Today, they are no longer from the East River, and you should be happy about that. They are from the Connecticut side of Long Island Sound, and of medium size, with medium brine. Think of them as a larger, saltier Bluepoint.
