Celery salt

Celery seeds can be ground and mixed with salt to produce celery salt. Celery salt can be made from an extract of the roots or by using dried leaves. Celery salt is used as a seasoning, in cocktails (commonly to enhance the flavour of Bloody Mary cocktails), on the Chicago-style hot dog, and in Old Bay Seasoning. Similarly, combinations of celery powder and salt are used to flavour and preserve cured pork and other processed meats as an alternative to industrial curing salt. The naturally occurring nitrates in celery work synergistically with the added salt to cure food.
