3-Step Execution Protocol

Preheat & Prep

Preheat boiling to 212°F (100°C) heavily salted water. Prepare fresh asparagus spears (blanched) (Medium spears (about 1/2-inch stalk), woody ends snapped off, whole).

Cook

Cook for 2–4 min (2 min pencil / 3 min medium / 4 min thick). Do not flip; allow surface to develop undisturbed.

Check & Rest

Color flashes to bright grass-green and the tip of a paring knife slides into the base of a stalk with a soft click of resistance — no bend, no mush. Rest for 0 minutes before serving.

Verification Basis & Testing Rig

USDA National Center for Home Food Preservation blanching chart for asparagus (2 min small / 3 min medium / 4 min large spears prior to freezing); technique validated by author testing on 1/2-inch spears with an ice bath.

Pro Tip: Have an ice bath ready before the water even boils. Asparagus goes from perfect to olive-drab army-canteen green in about 30 seconds of residual heat; the ice bath is the only thing that stops that clock cleanly.
