Avocados don’t freeze well!!!
Guacamole can be frozen if you don’t add the raw tomatoes or onions. These break down and make the guacamole watery. However, the avocado, salt, lime juice and maybe a bit of cilantro, will freeze well and you can add the onion, fresh garlic and tomato later. When filling into the bags, the goal is to get out the air bubbles that are trapped as best you can. Shake the guacamole to the bottom of the bag, then squeeze gently towards the top of the bag. Close the bag nearly closed, and work the guacamole up and toward the bag seal while squeezing out all the residual air. Close up your bag and press flat for easy storage. Incidentally, the lime juice keeps the guacamole from turning brown.
The frozen guacamole will keep in the freezer for 3 months. Thaw in the refrigerator. Thawing in the microwave is a bad idea.
