Slice or cut fruit into chunks. You can also cut fruit into smaller pieces and freeze ahead of time on lined baking sheets or use packaged frozen fruit. This will help keep the fruit and leafy greens from freezing together in a large clump and the smoothies will blend more easily.
Label bag and jar lids with recipe name and date. Be specific. You might also want to include how much of which liquid gets blended with each smoothie pack (to have when you're ready to blend).
Measure out the ingredients and pack into jars or bags.
Remove as much air as possible from bags and jars when sealing closed. Pack fruit and greens tightly into the jars and screw on the lids.
Place in freezer. Don't pack too tightly together. There should be some air circulation to help the contents to freeze quickly.
When ready to use
Remove smoothie pack from freezer. Add liquid base to container or bag (which helps defrost the fruit slightly). You can also thaw for a few minutes on the counter or in warm water. The fruit and greens will come out of the jar/bag easier too.
Pour into blender and blend until smooth.
Smoothie packs will keep for several months in the freezer but are the very best quality when used within 2-4 weeks.
If hoar frost forms on the fruit and greens, it is still perfectly safe to consume. It can be rinsed off with lukewarm water.
Store smoothie packs away from foods with strong odors. Glass jars offer the best protection against odors.
