1 box of pectin
1 package (6 ounces) raspberry gelatin

In a large stockpot, combine tomatoes, lemon juice, and sugar. Bring to a boil. Reduce heat; simmer 25 minutes, stirring occasionally. Add in 1/2 cup reserved sugar with pectin mix in (this prevents the pectin from clumping). Bring to a boil and boil for 1 min.

Spoon into jars to 1/2 inch headspace, wipe rims, and assemble lids.

Process in a boiling water bath canner for 10 mins.
