Get boiling water canner ready. Wash jars and lids. Have rings ready. Since this jam is processed in the water bath canner for 15 minutes the jars don't need to be sterilized, just washed in hot soapy water.

Mix all ingredients, minus the orange zest in a large stainless steel pot. Bring to boil stirring often until sugar is dissolved. Reduce heat and boil gently until most of the berries have popped and the sauce begins to sheet on a cool metal spoon - about 15 to 25 minutes. Add the orange zest during the last few minutes of cooking. Remember to stir continually.

Pour the hot sauce into the hot prepared jars, leaving 1/4" inch headspace. Remove any air bubbles with a wooden spoon or spatula and adjust headspace.

Wipe rims, place lids and rings on jars.

Process in a boiling water canner for 15 minutes, adjust time for altitude.
