No these are not the same. Essentially celery seed is a spice that is made from wild celery and is often sold both as seeds and as ground celery spice. Celery salt is a combination of both ground celery powder and salt. This is what you can buy in the stores. However, in the homemade celery salt version, we roast the fresh celery leaves and then break them down into a fine powder and mix it with your choice of salt. As result, we have fresh celery leaves and a salt seasoning blend.
