Wash jars in hot soapy water, first checking to ensure that the jars have no cracks or chips in them. Rinse well. Inspect the screw bands and discard any that have dents or rust on them. Use only brand-new lids for canning. Wash and rinse lids and set aside until needed. The lids give the jars the vacuum seal and are designed for single use only. Once they have been used, the rubber sealing compound is no longer considered effective for proper sealing so the lids should never be re-used. The screw bands, on the other hand, are reusable provided they have no dents or evidence of rust. Set out required pots and canner along with other equipment specified in the “Supplies and Equipment” section above.
After the mincemeat has been simmering for about 1½ hours, start sterilizing the bottles and preparing the hot water canner. Fill a large pot of hot tap water, about ¾ full. Place pint jars upright, into the water (include 1-2 extra jars in case they are needed to take up space in the canner so the filled jars do not topple over during processing). Ensure the jars are fully submerged, each jar filled with water, and that the water is at least an inch over the tops of the jars. Cover, bring to a boil, and boil for 10 minutes. Turn off heat and leave the jars, covered, in the hot water to have ready to fill once the mincemeat finishes cooking.
While the jars are sterilizing, fill the canner about half full of hot tap water. Cover and bring to a boil to have it ready for processing of the filled jars as they must immediately go into the canner to be processed while the mincemeat is still hot. Reduce heat to keep canner water hot until needed. When the mincemeat is ready to bottle, boil a kettle of extra water to have ready, if needed, to top up the canner water with boiling water after filled jars are added.
Center washed lids on jars so the sealing compound on the lid edges aligns with the jar rims. Fingertip tighten the ring/screw bands until resistance is encountered. Do not over-tighten.
Let jars sit in the hot water for 5 minutes then, using jar lifter tongs, carefully remove the jars filled with mincemeat, upright and one at a time, and transfer them to a heat-proof cutting board, that has been covered with a towel, to cool completely. Listen for the “pop” or “ping” sound as the bottles seal over the next few minutes or hours. The lids of properly sealed jars will curve downward. Let jars rest, undisturbed, on counter for 24 hours. Then, test each jar for proper sealing by gently pressing down on the center of each jar lid. If the lid is already pressed downward, and does not pop back up, it is properly sealed. Any jars that do not pass this test should have the mincemeat transferred to a freezer container and frozen for later use or, alternatively, refrigerated when cooled and used in a recipe within a few days. Store properly sealed bottles in cool, dark place. The mincemeat benefits from maturing for at least a month before using. This allows the flavors to develop and deepen. Refrigerate any leftover mincemeat for up to 5 days once jar has been opened.
Yield: Apx. 10 – 12 cups
NOTE: Exact yield is difficult to project as it depends on the quality and maturity of the green tomatoes, the rate and heat at which the mincemeat is cooked, and how cooked down the mixture is. The recipe should yield 10-12 cups so prepare 6 pint jars for the canning. At the end of bottling, if there is insufficient mincemeat to completely fill another bottle, either refrigerate and use the fresh mincemeat in a recipe within a few days or freeze it for later use. Bottles should be filled to ½“ from rim when preparing them for processing in the hot water.
