Hello, I'm Pete Dryden, and I'm going to show you how to freeze yellow squash. Things you will need: yellow squash, freezer bags, a large saucepan, a cutting board, and a knife. First step is to rinse the squash with warm water and place it on to a cutting board. Next, cut off the ends and slice the squash into small chunks. Now, fill a saucepan halfway with water and place it onto the stove. Turn the burner on to high and let the water boil. Add the squash to the boiling water and blanch for three minutes. Next, fill the sink with ice water. Now, remove the pan from the heat and pour it into the ice water. This will prevent the squash from being overcooked during the blanching process. After around three minutes, remove the squash pieces from the water and place them into freezer bags. Seal the bags tightly, making sure to remove all excess air, then place into the freezer. And that is how you freeze yellow squash.
