Step 1

Combine the cranberries, bell peppers, jalapenos, serranos, and vinegar in a large deep pot. Bring to a boil over high heat. While the mixture comes to a boil, shake together the calcium water according to the package directions. In a small bowl, stir together 1 cup of sugar and 1 tablespoon of Pomona's pectin.

Step 2

When the mixture on the stove is boiling, add the calcium water and sugar/pectin mixture. Stir and bring to a boil again. When the sugar and pectin have dissolved, about a minute of simmering, add in the remaining 5 cups of sugar all at once. Stir to combine and bring to a roiling boil. (A roiling boil will continue to boil across the entire surface even while stirring.)

Step 3

Allow the mixture to boil for 1 minute and then remove from the heat. Remove from the heat and pour into sterile jars. Process in a hot water bath and then store in a cool dark place for up to a year. The USDA recommends 10 minutes for jam and jellies with pectin.

Step 4

Alternatively, this jam may be stored in the refrigerator until ready to use. The jam will keep in the refrigerator for up to a month or alternatively, you can freeze it for up to 6 months.
