In cooking, celery salt may be substituted by mixing regular table salt with something celery-flavored, such as celery itself; lovage, an herbaceous plant; or celeriac, a lumpy brown root vegetable.
Commercially available celery salt is table salt mixed with ground celery seed, but not the seed of the variety of celery usually consumed in salads or as a snack. Instead, seeds of an ancestor of celery is used, called "smallage" or "wild celery." Sometimes an extract of celeriac is used in place of celery seed.
Uses of celery salt include Bloody Mary cocktails or as a flavorful condiment for corn on the cob or eggs.
