I assume it's fine to freeze fresh guacamole? How long does it keep? Any tips on how to defrost?
It can be done, if necessary...squeeze some extra lime or lemon juice over the top, and seal it in a double thick freezer bag with as little space and air as possible. I wouldn't keep it more than a month or so, if that long...not because it'll go "bad" but its texture will suffer over time. I would defrost it overnight in the refrigerator for best results.
I have had success using my vacu-sealer. I got the idea when I bought some prepackage guac from TJ's. The key is extra lime/lemon juice and to squeeze out any air pockets before using the vacu-sealer so that you can truly get all the air out. I personally would use it within 2 month.
I have also had success freezing peeled avocado halves. Toss in lime/lemon juice place on cookie sheet and put in freezer to almost frozen. Put in bag and vacu-seal as usual or place in Ziploc bag and squeeze out as much air as possible. Good for making a quick batch of guac!
I had an avocado tree that produced 250 creamy/delicious avocados...in November/December! (That's not a time of year when I'm really the mood for guacamole.)
I used to put my guacamole in containers, top it with lemon juice and freeze it. It just never tasted the same after being frozen--went from creamy to a fluffy/odd texture--just not very tasty IMO.
I would say that it is not going to be great when you take it out of the freezer.
For me, guac is just something you make if you have the fresh ingridients on hand. The frozen stuff (either store bought or from your own freezer) is not what you are looking for.
