Wash and pick over cranberries. Add the cranberries and apple juice to a medium-size saucepan.
Cook over medium-high heat until mixture comes to a boil. Reduce heat to medium and cook for 10 - 15 minutes until cranberries all popped and soften, stirring occasionally.
Pour the cooked cranberries in a food mill over a large bowl to separate the cranberry puree from the skins and seeds. (You could also use a blender to puree the berries and then use a strainer to strain the skin and seeds.) Rinse out and dry the saucepan.
Put the cranberry puree back in the saucepan and add the sugar and the liquid pectin. Bring to a boil over medium-high heat, stirring frequently. Boil one minute.
Allow mixture to cool slightly and then pour cranberry jelly into a bowl or a mold coated with nonstick cooking spray. Chill until set.
To unmold, dip mold in warm water for 5 seconds, then invert jelly onto serving platter.
Notes
Use two tablespoons of dry pectin. Mix the dry pectin with the sugar before adding it to the puree.
To unmold the sauce,fill a pot or large bowl with very warm water in the sink. Dip the chilled jelly mold in the water bath for at least 5 seconds. Then, immediately invert the mold directly onto your serving platter. If it doesn’t release, reheat the mold in the water bath.
You can use fun-shaped molds, a bundt pan, or even just a bowl to set and serve the jelly!
Fresh cranberries can be found in the fresh produce section of most grocery stores around the holidays. Pectin can be found in the canning section.
