Clean and cut the ends off the stalks.

Slice celery crossways cutting slices at about 1/4 inch thick.

Place evenly on dehydrator drying racks.

Set dehydrator at 125 degrees F and run it for about 10 hours. You can set the thermostat a little lower if you like and run it for 12 hours. When the celery is dry it should snap in half easily and you will have a bunch of little pieces,

Use a chopper, spice grinder, or blender to grind to a fine powder. Let your chopper run for several minutes until you no longer hear pieces clicking around inside the canister.

Use your celery powder to help boost the flavor of any dish that you are making when you don't want to add more salt, onion powder or garlic powder.
