What each ingredient does

Asparagus
The main vegetable, which softens and turns tender-crisp as it cooks in the boiling bath.

The step that matters

Boil the asparagus for 3 to 5 minutes based on thickness.. Heat softens the asparagus cell walls, so thicker spears need more time while thin ones need less. Boiling too long breaks them down and leaves the texture soft and mushy.
