RHUBARB JAM CANNING RECIPE RECIPES

Steps:

• Combine the sugar, lemon zest, and lemon juice in a small saucepan and cook over very low heat for 10 minutes, until the sugar is dissolved. Add the strawberries and continue to cook over very low heat for 20 minutes, until the strawberries release some of their juices and the mixture boils slowly. Cook until a small amount of the juice gels on a very cold plate. (I keep one in the freezer.) Pour carefully into 2 pint canning jars and either seal or keep refrigerated. Use immediately, or follow proper canning guidelines below.
• Sterilizing Tips:
• Jars should be made from glass and free of any chips or cracks. Preserving or canning jars are topped with a glass, plastic, or metal lid, which has a rubber seal. Two piece lids are best for canning, as they vacuum seal when processed.
• To sterilize jars, before filling with jams, pickles, or preserves, wash jars and lids with hot, soapy water. Rinse well and arrange jars and lids open sides up, without touching, on a tray. Leave in a preheated 175 degree F oven for 25 minutes. Or, boil the jars and lids in a large saucepan, covered with water, for 15 minutes.
• Use tongs when handling the hot sterilized jars, to move them from either boiling water or the oven. Be sure the tongs are sterilized too, by dipping the ends in boiling water for a few minutes.
• As a rule, hot preserves go into hot jars and cold preserves go into cold jars. All items used in the process of making jams, jellies, and preserves must be clean. This includes any towels used, and especially your hands.
• After the jars are sterilized, you can preserve the food. It is important to follow any canning and processing instructions included in the recipe and refer to USDA guidelines about the sterilization of canned products.

Steps:

• 1. Peel, core and dice pears. (Be sure to chop the pears relatively small, as they'll remain close to that size in the finished jam.) 2. Toss the pears in lemon juice and sugar, cover and refrigerate for overnight (12 to 24 hours). This step is important, and at an absolute minimum, they need 4 hours, preferably more. 3. Prepare a water bath canner (if canning, skip for a freezer jam). 4. Place pear mixture into a heavy-bottomed saucepan and bring to a boil on high. The mixture will foam, so be sure your pan is big enough to handle foaming to avoid overflows. 5. Stir the mixture occasionally, watching for overflows, and cook for about 10-15 minutes. If pear pieces are too large, crush slightly with a potato masher (optional). 6. Cook until the pear jam reaches gel stage, using an instant-read thermometer or testing a small amount on a plate placed in the freezer. (Gel stage is 220 degrees F at sea level and a bit below that at higher elevations.  The finished temperature drops by 1 degree for every 500 feet above sea level.  I'm at 1000 feet, so my jams finish at 218 F.) 7. Once the jam reaches gel stage, immediately remove it from the heat and pack it into jars leaving 1/4 inch headspace, sealing with 2 part canning lids. 8. Store the pear jam in the refrigerator for immediate use, or process in a water bath canner for 5 minutes. Turn off the canner and allow the jars to sit an additional 5 minutes before removing them to a towel on the counter. Check for seals after a few hours, and store any unsealed jars in the refrigerator. Canned pear jam should last 18 months or more at room temperature if properly sealed (refrigerate after opening) Refrigerated jam should last at least 2-3 weeks.
