Basic Tips on Freezing:
Organize your freezer. You want to make sure you have enough space for your frozen goods and that you know where they are when you need them!
Though not strictly necessary, it's worth taking the time to quickly blanch vegetables in boiling water. This helps retain firmness in the vegetable and prevent discoloration. This is also necessary for wilting down leafy greens, which can then be chopped and frozen.
Slice your fruits and vegetables into bite-sized, uniform pieces before freezing. Not only does this make for better freezing and thawing, but it also makes things easier for you later on since all you'll have to do is pop open a container and add it to your dish.
If possible, spread your sliced vegetables or fruits in a single layer on a sheet tray and freeze until they're at least partially frozen before transferring them to individual containers. This helps the produce freeze more quickly and evenly, and it also prevents individual pieces from adhering to one another.
Try to keep a consistent temperature in your freezer, particularly while foods are first freezing. This also helps food freeze more evenly and prevents frost from building up on the food surface.
Don't forget to label containers with the contents and the date. Frozen fruits and veggies are good for up to a year, though their taste and texture can start to deteriorate after a while due to freezer burn.
