How to prepare asparagus
Start by washing gently under running water to remove any sand or dirt, then trim or snap off the woody ends of the spears. Cutting this end into a point, by making slanted cuts at the bottom of the spear on two sides to thin it out, will help to make the tips and spear cook in the same amount of time. You may also wish to peel the thicker stems. Start removing the outer skin about 1.5 inches below the tips, down to the base.
With a small, sharp knife or an Asparagus peeler
trim off the pointy bits from the spear so that no sand can stay trapped underneath them.
If you are boiling or steaming the asparagus you can put several spears together and tie them into a bundle. If they are to be grilled or broiled, keep them separate.
That's the preparation done! You are now ready to learn how to cook asparagus.
