You start with uncooked asparagus correct?
I ONLY microwave steam my asparagus. I clean and rinse them, then place them in a container, nothing added to them at all, cover and steam just till tender crisp. I steam just about all my veggies this way including corn on the cob. Veggies have enough moisture none is needed. There are several exceptions - I DO added water to steam artichokes and I boil taters for mashed.
All our times have come. Here, but now they're gone.
Seasons don't fear the reaper.
Nor do the wind, the sun or the rain.
We can be like they are.
