Pretzel

Pretzels are an Earth food, cooked shaped dough usually served covered in salt.

The 602 Club often had bowls of pretzels sitting on the bar. 

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.
