Anna, found an easy cranberry jam on line.
Homemade Tart Cranberry Jam in Ten Minutes
Ingredients
1 pound frozen or fresh cranberries
1 2/3 cups sugar if you prefer a sweeter jam, you can add more sugar
1/2 teaspoon butter
1 teaspoon orange zest optional
3 tablespoons liquid fruit pectin be sure to use the liquid kind and not the powdered kind
Instructions
Crush the cranberries in a food processor until you have cranberry mush (if they are frozen, it will be more like cranberry powder).
Bring the cranberries, sugar, and butter to a full rolling boil in a medium-sized heavy-bottom saucepan on high heat, stirring periodically.
Quickly stir in the liquid fruit pectin.
Boil for one more minute.
Remove from heat, store in a bowl, Tupperware, glass jar, or whatever you'd like in the refrigerator.
Use however you would use jam.
