Snap or cut off tough ends of asparagus spears. In 12-inch skillet, heat 1/2 inch water (salted if desired) to boiling. Add asparagus; reduce heat to medium-low. Cover; simmer 2 to 3 minutes or until crisp-tender. Drain. Plunge asparagus into bowl of ice water to cool; drain on paper towels. Refrigerate until ready to serve.
