Ground celery powder is a dried, ground concentrate prepared from fresh celery that is used as a seasoning and as a food preservative. Celery powder made from celery seed will have the herbaceous and savory flavor of celery but slightly more intense and with a hint of bitterness. Along with being a popular flavoring in many classic American dishes like potato salad, celery powder can be used to flavor sauerkraut and salad dressings. It is also a popular flavoring for Bloody Mary cocktails. You can use it in barbecue rubs and for pickling. Too much ground celery can overpower a dish, whereas a little enhances the flavors in other foods. Ground celery is able to blend smoothly into spice blends, soups, sauces, and condiments without the addition of texture if you used whole celery seeds.
