Thanks, all! I'll check TJ first. I need to make a run to WF at some point in the next couple of weeks, so I'll check out what they have, too. I was hoping for frozen (don't really want to deal with the syrup in jars) but I'm sure the jars are fine.
Vons et al. carry a dried tart Michigan cherry by Oceanspray that are great if you are going to cook with them. A soak before in something intoxicating or as the are if the dish contains liquid does the trick.
Whole Foods usually carries jars of them (labeled as "tart" cherries). i think they're in the baking/spice aisle...? call La Jolla & Hillcrest to find out if either store has them.
