This method is not recomended as the carton can bust as the juice expands. Additionally, it is not as protective as freezer safe containers or freezer bags. But, when short on time it can work.
Simply toss the unopened store-bought carton into the freezer
note:1) if you want to avoid pressure on the carton, open it and pour an inch or two out before freezing it.2) For extra protection, pop the whole carton into a freezer bag before putting it in the freezer.
Freezer Safe Container or Freezer Bag
Portion the juice out into how much you will want to use when thawed.
Pour the juice into a freezer safe container or freezer bag.If using a container, use one that will only have 1 - 2 inches of space between the juice and the lid.
Carefully zip the freezer bag up after squeezing any air out of the bag. Or, secure the lid on top of the container.
Label the outside of the package with the date and lay it flat in the freezer.
Ice Cube Tray
Pour the orange juice into the holes in the ice cube tray, leaving a little space at top of each hole to accommodate expansion when frozen.
Place the tray into the freezer for a few hours, until it is frozen.
Remove the tray from the freezer and pop the frozen juice cubes out.
Toss the frozen cubes into a freezer bag or freezer safe container.
Seal the package up by zipping the bag closed, after pressing any air out of it. Or by placing the lid on top of the container.
Write the date on the container or package and toss it into the freezer.
Notes
Portion it out: make sure to portion out the orange juice into the amount you will need when defrosted. That way you can just thaw the right amount each time.Do it Fresh: the fresher the orange juice is when you freeze it, the better the quality will be at defrosting.No pulp: pulp gets a little dried out when it is frozen and thawed. So, if you want the best possible texture, strain all the pulp out before freezing.Keep out air: the less air exposure it has, the longer the quality will last in the freezer. make sure there is no air in the freezer bag when you close it. Or, if using a container, try to leave juts 1 - 2 inches of space between the juice and the lid.
