When you are ready to use them thaw in the ice box overnight. These are great for guacamole, homemade baby food, chocolate mousse, truffles and so much more!
Google will not allow me to post a comment or reply to any of them left unanswered! So I'm catching up on all the comments and posting this note (9/22/12). Thank you all for taking the time to submit them and all the fabulous suggestions! As you can see in the photos above only the top of the sliced half turned brown. Underneath it was still green. I'm not too picky though so it really doesn't bother me what color it is, as long as it still tastes good : ) I mostly use the frozen in raw desserts, baking (you can use to replace a fat in a recipe) and guac. I haven't had any problems at all. Only thing I can think of as to why it wouldn't work is if the freezer temp isn't cool enough.
