I use a Foodsaver. That thing has paid for it's self many, many times over!!
For my basil, I put it in the food processor and ground it up with just enough EVOO to make a thick paste. Then I spread it on a cookie sheet about 3/4" thick and scored it with a spatula into small squares that had roughly 1/2 to 3/4 cup in it. Put it in the freezer till frozen. Take out of freezer, break into chunks along scores and Foodsaver each. They store nice and flat. I just used some of the pesto that I made last summer in the "food porn" pictures that I posted in the Photo section. I did roasted red peppers this way too.
Just recently I was diggin through the freezer and came across some pork chops that had gotten shoved to the back. They were just over 2 years old. I thawed them out and there was no freezer burn and they tasted like they were fresh. Foodsaver is a $$ saver.
(No, I don't work for Foodsaver,
I just think it's a great kitchen tool that is well worth investing in.
