Wash and pat dry your herbs with a kitchen towel and remove all moisture.
Chop up some fresh garlic along with the herbs using a sharp knife.
Top with the coarse salt and continue chopping.
Crush the salt, garlic and herbs using the flat edge of your knife. Do this for 2-3 minutes to get all the herbs and garlic nice and smushy.
Spread this mixture on a baking sheet lined with parchment paper. Cover this up with a thin muslin cloth and let it dry overnight.
Store the finished salt in a glass jar or an airtight container and use whenever you want to.
Notes
I really wanted to try making a coarse salt this time, so I skipped blitzing it. If you want to keep it simple and stick to the classic smooth texture, you can process the salt in your food processor or blender jar until you get those perfect texture to sprinkle.
If your mixed herb salt isn't drying even after a day, you can quicken up the process and pop the baking sheet into an oven preheated at its lowest setting, and let the salt dry up in there. This should take anywhere between 20-40 minutes, depending on how much moisture the salt has.
I would recommend storing the salt for a couple of days before you use it. Doing this will allow the flavors to deepen, and you'll get a more powerful punch of flavor.
