Two Tips for Managing Frozen Tomatoes
Freeze tomatoes in serving size containers. One quart freezer bags work well, as this quantity goes well in most soups and stews. When it’s time to use them, you simply warm the bag a bit either by sitting it out at room temperature for 30 minutes or so, dipping it in water, or zapping it in the microwave for 30 seconds. With that the block of frozen tomatoes easily slides out of the bag to go into the soup.
Freeze tomatoes on a cookie sheet. Once they are firm, transfer them into freezer bags or containers of any size. Now you have individual tomatoes you can use as needed.
