Should asparagus be cut or snapped?
The thicker the spear, the more pronounced the difference when snapped. THE BOTTOM LINE: You’ll throw away more asparagus if you snap off the ends, and the spears won’t look as long and elegant. For many reasons, we think trimming and peeling is worth the effort.
