How to Wash Parsely - as part of the expert series by GeoBeats. I have got a bunch of parsley here. This is Italian flat leaf parsley, which is my favorite. I prefer it more than curly leaf. Parsley has got to be washed. Just hold it under running water, like this. Shake a lot, and now you put it on a paper towel. Next step is damp dry it. I use a kitchen towel, and I just press down like that. That will take most of the water away, and you have got your washed parsley and it is pretty dry. Now, as far as it comes to actually using it, you want to remove the leaves. The stems of parsley you do not use, although you can save them if you are making stock. It is a wonderful flavoring agent, but for most dishes it is too bitter and too tough. So, you do not want the stem. Then you simply chop the parsley however the recipe describes you will need it. With the remaining parsley, the best thing to do is back into the plastic bag and into the crisper drawer of the refrigerator. Use it as you need it.
