Pick chive blossoms off of flowering chive heads to make 1/3 cup of blossoms.
In a medium bowl, stir the salt, chive blossoms and lemon zest together until they're evenly distributed.
Spread the mixture onto a large plate lined with a paper towel.
Let it dry for about 4 days, or until the blossoms feel "paper-y" to the touch.
Stir the mixture once daily to ensure even drying.
Once dried, transfer the chive blossom salt into a clean, dry jar with an airtight lid or package into spice jars and label to give as gifts.
Store in a cool, dry place for up to 1 year.
