Stalk celery is the perfect ingredient in stews and soups. I often use it for stock and vegetable salts too. If you really like celery, you might also be interested in putting them into smoothies or making celery juice. Or why not add a few fresh stalks for your salads? My best tip is actually to put celery stalks in fish stew. It's so good! You can freeze your celery too if you happen to grow a bit too much. Cut in smaller pieces and freeze raw.
