1Mash 13 cups whole berries
2Add powdered pectin, lemon juice and cinnamon, stir until dissolved

4Add Sugar and stir in to dissolve
5Bring back to boil for another 3 minutes
6test jam for consistency. For this step I keep a tablespoon in a glass of ice water near the stove. spoon out about a half tablespoon of the jam out of the boiling pot, and let it cool on the spoon. Then turn the spoon up on edge. If the jam either sticks to the spoon or falls off in a lump (as you would expect jam to do!), then it's ready. If it runs off like liquid, keep boiling another 1-2 mins and try again.
7Remove from heat and ladle off any foam. The foam won't hurt anything, it just looks more appealing int he jar without it.
8Let stand for 5 mins. This little trick prevents the fruit from floating to the top of the jar, plus it's about the right amount of time to get your jars and lids out of the pot/dishwasher and set them up to fill.
9Fill jars to within 1/4 inch of the top. Be sure wipe the top edge of the jar with a clean cloth to remove any jam or it will prevent proper sealing.
10Add metal sealers and rings and tighten down fully.
11Within 1-2 hours all the seals should 'pop' on the jars. A good way to check is to try and push down the center of the metal sealer lid. If it flexes it's not sealed, if it has no give...you're good!
