For the turnips, dice and water blanch for 2 to 3 minutes. Be sure to give them an immediate ice water bath after the blanching to stop the cooking process. Drain, pat and remove as much air from the freezer bag as possible to reduce freezer burn.
When ever my Mother had a few extra tomatoes she would wash them, remove the stem and toss them in a plastic bag in the freezer. Then when she wanted a couple for something she was cooking, she would remove however many she needed. Rinse them under warm water and the skin would rub off, then put them in whatever she was cooking and as she stirred them into the pan, she would break them up.
