Step 1

Turn your oven on to its lowest temperature setting. Line a baking sheet with parchment paper.

Step 2

Place the celery leaves on the baking sheet and put them into your oven - no need to wait for your oven to come up to temperature. Dehydrate them for 15-25 minutes, depending on your oven's lowest temperature. They are done when they're dry and crumble easily.

Step 3

Crumble the dry celery leaves into a powder with your fingers and remove any pieces that are hard or not fully dry.

Step 4

Mix the celery leaf powder with salt and transfer it to a non-metal jar for storage.
