1. In a large saucepan, combine berries, pectin and lemon juice. Bring to a rolling boil, stirring occasionally.
2. Add sugar and bring to a boil again; boil exactly 1 minute, stirring constantly.
3. Remove from heat. These preserves can be canned or kept in an airtight container in the refrigerator up to 8 weeks.
*TIP: To can, ladle hot preserves into hot, sterilized half-pint canning jars, leaving a 1/4-inch headspace. Wipe jar rims; adjust lids and screw bands. Process filled jars in a boiling-water canner 5 minutes. (Start timing when water returns to a boil.) Remove jars; cool on wire racks.
