Blueberry Jam
Modified from Pick Your Own

1/4 cup lemon juice
1/2 cup water
4 1/2 cups sugar
1 1/2 box no-sugar added pectin (the pink box)
Sterilize the jars. Crush berries. Measure sugar and set aside 1/4 cup sugar and mix with pectin. Mix blueberries and pectin/sugar and bring to a full boil. Add rest of sugar and boil, hard, for 1 minute. Test jell. Fill and process (check times, they change due to altitude). Remove and cool.
