Wherever you'd use celery, you can use celery seed instead. Celery stalks retain their stringy quality when cooked, which can detract from delicate dishes like soups. Celery seeds tastes exactly like celery.
Celery Seed and use:
Use Celery seed in making pickles. Add to coleslaw, potato salad, macaroni salad, egg salad, meat loaf, fruit salad dressing, salmon loaf, and chicken dishes. Celery seeds are also a great source of calcium, and are regarded as a good alternative to animal products. Celery seed is available mixed with salt. Celery Salt can be added as a seasoning on Chicago style hot dogs and in a bloody Mary cocktail. Use it for flavoring soups, stews and sauces, or rub it on steaks.
