The asparagus ends can also be trimmed off at the bottom by using a knife. First find the area where the green color begins to fade. This is where the tough woody end begins and is where the stalk should be trimmed off. Snapping the ends off breaks them off at the point where it becomes tough so you do not have to visually guess where to cut them.
After removing the asparagus
ends, the stalks can be cut to varying lengths or left as whole spears. Do not remove the spears at the top of the stalk. If it is important for presentation purposes that the spears be the same length, line them up flush at the top and trim them off at the bottom so that they are all the same length. If appearance is not critical, do not trim to even lengths because this ends up wasting some of the good asparagus spear.
