How to successfully crack, shell, and eat a pecan:
Step One:
Find a good one. Don't be too picky and don't worry about dirt on the outside, the good stuff is on the inside.

Step Two:
Crack it open. Use too much force and you'll crack the goods on the inside; not enough force and you won't make it to the next step.
Step Three:
Peel away the cracked portions and enjoy.
