A pound or so – of Rainier cherries, pits reserved. (You can use Bing or even sour cherries)
Half strength simple syrup (For every C. sugar, add two C. water)
Dark rum (one T. for each half-pint jar you end up filling)

Pit the cherries.. Do this over the pot you’ll be cooking in, and just drop the pits into the pot along with the cherries. The pits will give the cherries a slight amaretto flavor. Add in the sugar and water, and bring to a boil for five minutes. Remove the pits, and scoop the cherries into sterilized jars. Add one T. dark rum directly to each half-pint jar, then ladle in enough syrup to cover the cherries, leaving 1/2 inch of headroom. Seal the jars with sterilized lids and rings, then process in boiling water for 10 minutes.
