Place the asparagus in a microwaveable dish. Add two Tablespoons of water per pound. Cook at full power for 1 to 2 minutes, or until bright green and still crisp. After blanching, cook immediately in ice water. Drain well and pack in plastic freezer bags or containers, leaving no excess air space. Seal, label and freeze at 0° F. Use within 8 months for best quality. Do not defrost before cooking. If asparagus becomes defrosted, cook immediately. Do not re-freeze.
