Cut the tops and bottoms off each head of celery. Place the individual ribs of celery in a sink or tub filled with cold water. Rub and rinse any dirt or debris that may be on the celery stalks. Drain the celery well and pat dry to remove as much water as possible.
Wash, rinse and dry well with a lint free towel the dehydrator trays to remove any residue or stickiness that may be leftover from the last time you used them.
Dehydrate the celery
When dehydrating celery, it's best to cut it into thin slices as this will help it to dehydrate uniformly. Using a sharp knife, cut the celery stalks into thin slices, approximately ¼ inch thick. Consistent thickness ensures that the celery will dehydrate evenly.
Preheat your dehydrator to 125°F to 135°F. The temperature range should be within the recommended range for celery. Dehydrating at too high a temperature can cause the vegetable to cook instead of drying evenly. Also, dehydrating at too low a temperature can lead to the growth of bacteria and mold.
Arrange the sliced celery pieces on your dehydrator trays. Ensure there is some space between them for proper air circulation. Don't overcrowd the trays as this will lengthen the drying time.
Slide the trays into the dehydrator and close the lid. Dehydrate the sliced celery for 8 to 12 hours or until the pieces are dried and crispy. Check frequently.
Once the celery is properly dehydrated, it's time to store it away. You can either store it in a mason jar, a ziplock bag or a vacuum-sealed container. Ensure that the container is airtight and kept in a cool and dry place. Dehydrated celery can last for months and even years if stored properly, ensuring you will always have some on hand for your recipes.
