1In a large saucepan combine cherries and sugar. Bring to a boil, reduce heat and simmer until cherries have given up their juice. Remove from heat and push through a sieve to remove skins and pits. Return cherry juice to saucepan over medium heat, add all the dry ingredients, stir well and bring to a boil. Reduce heat to a simmer and add 1 cup maple whiskey. Continue to simmer until slightly thickened. Remove from heat and stir in the final 1/2 cup whiskey. Cool and refrigerate in a sealed container.
