Carefully cut the avocado in half vertically, then use a spoon to scoop out the pit (seeds). Remove any surrounding flesh or sticker residue with your fingers. Compress each avocado half with plastic wrap to make them solid. If you want, you can peel off some of the skin first if it makes it easier to pack more portions together at once; this doesn’t affect flavor or nutrition. Wrap each sufficiently-compressed half in plastic wrap tightly enough that they won’t fall apart when moved or touched mistakenly but not so tightly that they cannot be unrolled for consumption later on after thawing and it will last just as long as before – even 24 hours later!
