First cut brocolli up into bite size pieces.
Don't forget to save the stems for juicing.
Bring a pot of water to a boil.
Add brocolli and when it comes back to a boil, time for 3 minutes.
Quickly drain the brocolli and then plunge it into an ice water bath to quickly cool it and stop the cooking.
This process of partially cooking and then quickly cooling is called blanching.
When brocolli has cooled, drain, pack and label.
