I was at the local Aldi and found jars of Morello (sour) cherries on the seasonal aisle. These are the cherries called for in Martha Washington's Cherry Bounce recipe and are usually hard to find. They're already jarred in light syrup so that cuts out several of the steps necessary for using fresh cherries. I made up a batch last night and it's really nice. I'm going back to load up on them before the seasonal aisle changes.
