Remove any leaves and stems that have gone bad- sometimes there are none and sometimes there are a few. They will be brown or black in color.
Cut off the long stems. The stems are the parts that don’t have any leaves coming off of them. They are thicker and are typically ⅔ rds of the bunch.
Chop cilantro to desired consistency. Start at the top of the cilantro bunch and with a rocking motion chop the cilantro from top to bottom, then from side to side. Repeat until chopped to your desired consistency.
