Red, White, and Blueberry! Happy Fourth of July!
As promised, the jam I made last week is here for you to see. The recipe could easily be titled 3B Jam! Although most of my small batch preserving goes into the refrigerator for safe keeping, I acutally put these jars into a traditional hot water bath for 10 minutes, sealing them nicely for storage on my pantry shelf. A number of ways to set up water bath canning make it easy for anyone to do. If you have a stock pot with a circular rack that fits the bottom and a fitted lid, that will work. There are canning sets available from multiple sources, for prices that range from $ to $$$. Let me give you the short version! You can go online and order a large blue granite (enameled) pot with handled rack which handles all sizes of jars) to be picked up onsite at Walmart for $19.99. Or, if you have a stockpot already, go to Sur le Tables and buy only the rack for $11.99. I liked this option because 1)I don’t need another big pot to store – 2) this rack has 2 sides: one holds 7 8 or 16 oz. canning jars, flip it and the other side will hold 4 quart jars. This is perfect for most of the smaller amounts that I usually have when I make jam or jelly.
8-10 cups fresh blueberries
4 1/2 cups sugar
1 box Certo liquid pectin, both packets
1 tablespoon black pepper
7-8 8 ounce Mason jars, or other glass canning jars. Avoid using recycled food jars.
Lids and Rings to fit jar size you are using. Always buy new lids if you are going to seal them in a water bath for shelf storage.
large stockpot for water bath
separate pot for cooking berries
large bowl for mashing berries
long-handled wooden spoon
wide mouth funnel for filling jars
Wide tongs for lifting jars out of water bath. (these can also be bought where other canning supplies are sold)
Pour the berries into a bowl and mash with a potato masher. A blender or food processor will overdo the crushing, so just muster up the elbow grease for this job. It is almost as good therapy as kneading bread! Measure it out. There should be about 6 cups of mashed berries. Add sugar and blueberries to a large pot. It is a good idea to have a pot big enough for berries to only fill about 1/3 full, as ingredients will tend to boil over in smaller pot.
If you are using a water bath, fill the large stockpot to a level that would be 1 or 2 inches above jars when placed on rack. Start heating to a boil. This takes a long time.
Prep jars/lids for canning. I like to put all into the dishwasher and run a sanitize cycle, then place the jars upright while still hot on a towel. Lids should be put into a bowl covered with very hot water.
Stirring occasionally with a long-handled wooden spoon, bring the sugar and blueberries to a boil. Boil for about 10-15 minutes. Stir in the pectin. Continue cooking at a low (rolling) boil for 5 minutes. Stir in the vinegar and pepper. Fill the jars, wiping off lids and threads. Place lids on top and screw on rings. When stock pot water is boiling, lower the jars to rack and process in the hot water bath for 10 minutes. Remove the jars carefully, setting them upright on a towel very gently. Leave overnight, during which time you may hear the popping of lids as they seal. In the morning, press down on the center of each lid. If the lid pops back up, it did not seal, and that jar should be refrigerated for storage. Tighten screw rings again, wipe off any sticky on the jars, and label if you wish.
Yield: about 7 8-oz jars
Note: A good source of canning information is the Blue Book guide to preserving. There is also good information on the information sheets packed inside Certo boxes.
