Really, the easiest is cutting it off raw and then cooking it. trust me. works much better. then cook it just until the color goes from opaque to clear no matter whether it is white, yellow or bicolor and then measure it into 1/2 servings per bag of how many you normally feed for dinner and then freeze it. I use a corn zipper. it is the best tool I have found so far.
