Place herbs onto wire racks on baking sheets. Amount of herbs used is up to you. More herbs will give your salt or sugar a bolder flavor.
Place the baking sheets in the oven on the lowest heat and dry the herbs for 45 minutes.
Once the herbs are dried, take them out of the oven and allow them to cool.
Place salt or sugar into small mixing bowl. Remove the herbs from stems and add to mixing bowl.
Mix the herbs and salt/sugar by hand, crushing the herbs to release their oils.
Then, spoon or funnel the herb salt/sugar into sealable containers.
Store in a cool, dry place.
