Broccoli, a member of the cabbage family, is green to purple-green in color and has tightly clustered flowers, or florets, borne on sturdy stalks. The florets are the most tender part. The stems, if peeled, can also be used. Choose firm stalks and closed heads with deep color and no yellow areas. Refrigerate in a plastic bag for up to 4 days.
To trim broccoli florets:
Slice off the stalks just below the clustered flowers, or florets. Separate the florets.
