If you’re fancy and have a food saver, use it. Vacuum-sealing is the nuclear option. It removes all air, and the avocado stays perfect for up to a week.
But let’s be real: most of us are just using a plastic bag and sucking the air out with a straw. That works. It’s weird to do in front of guests, but it works.
Just don’t smash the bag. You want to preserve the shape, not make guacamole before you’re ready.
