Note: Dried lemon zest is also called dried lemon peel. Some stores sell it online, but you can also prepare it at home. To prepare it, remove zest from one lemon (not using the white part), then let zest dry naturally for 2 days, on a plate. You can also preheat the oven to the lowest temperature possible, place zest on a non-sticking baking pan and bake to dry it out (5 minutes or less might be enough). There Is also a third option, if you are in a rush, you can use regular lemon zest, however, your spice will only keep for several days if using the zest fresh.
