Spoon 1 cup of cottage cheese into each freezer bag.
Seal the freezer bag but leave the corner of the bag unsealed. Press the bag gently to remove as much as air as you can.
Straw "vacuum seal" trick (optional): Slide a straw into the bag and suck out the air so the bag "shrinks" around the cottage cheese. Slide the bag down the straw as you inhale, and quickly seal the bag while you remove the straw.
Seal the bag completely. Then, put this bag into another freezer bag, press out as much air as you can, and seal it.
Write today's date on a freezer label, stick it to the bag, and place the bag in the back of your freezer.
