Rinse your stalks and cut off the end 1.5" and discard. Then I prefer to cut the upper stalk into thirds, it is easier to eat that way and faster to cook.
To get the best overall texture it is best to blanch first, but this can be skipped if you choose to.
To blanch, in a pan add 1.5 cups water over medium high heat until it reaches a boil. Add asparagus trimmed and cut into thirds into the boiling water for just 2 minutes, then remove and transfer into a bowl of ice water for just 1 minute. Use a slotted spoon to remove and move on to a few paper towels to dry outsides.
Use a different pan, or wipe the one with water in it dry and heat over medium flame with your butter until it melts.
Add asparagus pieces, sprinkle with seasonings and cover with a lid and "fry" for about 3-4 minutes (5 if you don't blanch first) or until they are as tender as you'd like.
