Measure the prepared cherries into a large, heavy kettle. Add the sugar and stir well. Place over high heat and, stirring constantly, bring quickly to a full boil with bubbles over the entire surface.
Add the remaining ingredients except the pectin. Boil hard for 1 minute, stirring constantly.
Remove from the heat and add the pectin. Skim off any foam.
Ladle into 8 hot half-pint jars. Seal, then process for 4 minutes in a hot water bath, counting the time from when the water comes again to a rolling boil after immersing the jars.
Final Comments
