Fill a pot with water and bring to a boil. Fill a large bowl or pot with half ice and half water. When the water comes to a boil, add the broccoli florets using a strainer with a handle if possible. Allow the broccoli to cook for 1 to 2 minutes until just tender. Immediately remove from the boiling water, using the strainer or draining, and transfer to bowl of ice to stop the cooking process. Immerse the broccoli completely in the ice water for a minute or two. Remove and place in a dish that has been lined with paper towels. This part can be done up to two days in advance.
