You can use it as is, but I find it is a lot more effective for certain dishes if you grind it to a finer consistency. I have a coffee bean grinder that I reserve for just herbs and it works like a dream.
If grinding, grind for less than 30 seconds to get a finer consistency as shown in the photo above.
