An easy jellied cranberry sauce recipe offered by Ocean Spray calls for using frozen cranberries as the basis. Another option is cooking fresh cranberries in a pressure cooker and using the cooked berries as the jelly foundation.
To make Ocean Spray's easy jellied cranberry sauce, mix 1 cup sugar and 1 cup water in a saucepan. Bring to a boil, stirring to dissolve the sugar. Add 12 ounces of frozen cranberries, and return to a boil. Reduce the heat so the water is boiling gently, and cook the cranberries for 10 minutes. Stir occasionally.
Place a wire mesh strainer over a bowl. Pour the cranberries into the strainer, and mash the cranberries with the back of a spoon until the pulp is gone. Remove the strainer, and stir the cranberry mixture. Pour into a serving container, and refrigerate until ready for use.
For an alternative cranberry jelly, wash and pick over 6 cups of fresh cranberries. Add the cranberries and 1 cup apple juice to a pressure cooker, and cook for five minutes. Strain the cranberries as described above. Place the cranberries in a saucepan. Add 2 cups sugar and 3 tablespoons liquid pectin, and bring the mixture to a boil. Boil for one minute, and remove from heat. Cool the mixture, and pour into a serving dish or molds.
