I have made this more than once. Kind of like a sweeter version of catsup, but better tasting. Yield: about 9 medium glass jars
3 cups prepared organic tomatoes (about 2 1/4 pounds ripe tomatoes)
1 1/2 teaspoons grated organic lemon rind
1/4 cup lemon juice (2 lemons)
6 1/2 cups (2 pounds 14 ounces) granulated organic sugar
1 bottle pectin "Certo" (I think that's the 2 packages that come in the box nowadays, check with Certo if unsure)
First prepare tomatoes. Scald, peel, chop the fully ripe tomatoes. Bring to a boil and simmer 10 minutes. Measure 3 cups of that into a large saucepan. Add the lemon rind and juice to the tomatoes. Add the exact measure of sugar and mix well. Bring to a full rolling boil and boil hard for 1 minute, stirring constantly. Remove from heat and add pectin. Skim off foam with metal spoon. Then stir and skim for 5 minutes to cool slightly and prevent floating "fruit." Ladle into sterilized glass jars, leaving 1/2 inch space, tighten lids and process in boiling water bath for 10 minutes.
