Pretzel
From Memory Alpha, the free Star Trek reference
A pretzel was an Earth food which consisted of cooked, shaped dough and which was usually covered in salt.
The 602 Club often had bowls of pretzels sitting on the bar. (ENT: "First Flight")
Doctor Phlox, Lieutenant Reed, and Ensign Mayweather once visited a bar that served pretzels. After Phlox puffed up his face to frighten a xenophobic Human there, he sat down and nonchalantly ate a pretzel. (ENT: "Home")
