How to Store:

To Freeze from fresh:
Preparation: Select firm, ripe tomatoes with deep red color. Frozen tomatoes will have a mushy texture when thawed and are suitable only for cooking, i.e. in soups, stews, spaghetti sauces, etc. In addition, tomatoes that are frozen raw become watery and develop an off-flavor after a short period in the freezer. Tomatoes that are too ripe for safe canning, but still sound and free from decay, can safely be frozen.
Blanch: Wash and dip in boiling water for 30 seconds to loosen skins. Core and peel. Freeze whole or in pieces. Pack into containers, leaving 1-inch headspace. Seal and freeze.
Juice: Wash, sort and trim firm, vine-ripened tomatoes. Cut in quarters or eighths. Simmer 5 to 10 minutes. Press through a sieve. If desired, season with 1 teaspoon salt to each quart of juice. Pour into containers, leaving 1-1/2-inches headspace. Seal and freeze.
Stewed: Remove stem ends, peel and quarter ripe tomatoes. Cover and cook until tender (10 to 20 minutes). Place pan containing tomatoes in cold water to cool. Pack into containers, leaving 1-inch headspace. Seal and freeze.
Tomato products such as sauce, puree, catsup and chili sauce can be frozen. Prepare as usual, cool rapidly, pack into rigid containers, leaving headspace, and freeze.
Select firm, sound green tomatoes. Wash, core and slice 1/4-inch thick. No blanching is necessary.
For later frying. Pack slices into containers with freezer wrap between the slices. Seal and freeze.
