Fruit juice jelly

I always loved apple jelly, but any 100% fruit juice/blend works.

4 C unsweetened apple juice
1/4 C lemon juice
1 1 3/4oz pkg powdered fruit pectin
4 1/2 C sugar

Pour juices into heavy pot.  Sprinkle with pectin and let stand for 1-2 minutes, stir to dissolve.  Bring to a full rolling boil over medium high heat, stirring frequently.  Stir in sugar and return to a full rolling boil, stirring frequently.  Boil hard for 1 minute, stirring constantly.  Remove from heat, skim off foam with a metal spoon.

Ladle into half pint jars leaving 1/4 inch headspace.  Process in boiling water for 5 minutes, remove jars and let cool until set.
