Sterilize canning jars. Combine ingredients in a saucepan large enough for free boiling and stir to dissolve sugar.
Bring to a full rolling boil and boil 7 to 8 minutes, or to 220°F. Remove from heat and skim foam.
Fill hot sterilized jars quickly, leaving 1/4-inch headspace; wipe rims and apply lids.
Process half-pints or pints 10 minutes at 0–1,000 ft, 15 minutes at 1,001–6,000 ft, or 20 minutes above 6,000 ft.
