I have tried them and yes they are quit good IMO. The name of this burger is "Pleevalean".
Your first thought that cherries are a fruit that and there presence in a burger will impart a strange flavor. That's not the case. The cherries are ground with the meat together and when cooked tend to hold the juices in the meat allowing leaner burger without the dry texture you get when you cook really lean ground sirloin. The cherries add a fair amount of water that is retained in the patty as it cooks. They do sell the patties frozen in some supermarkets in MI and If you follow this link I'm sure they will accept an order from you cn-line and ship them to N.Y. http://www.plevas.com/
Heres how Ray describes his product on the website.
Plevalean’s tasty mix of cherries and ground sirloin mean you get a lean, juicy and tasty burger that is lower in fat and calories. One Plevalean patty has only 140 calories and only 60 of those are from fat. It’s one of the reasons that schools in 18 states now choose Plevalean for their lunch programs. Another reason – great taste!
You can also go to Ray Pleva's retail Meat store located in Cedar, MI right the heart of the Traverse City Tart Cherry capitol. http://www.plevas.com/where_to_find_us.htm
I believe Ray also makes a delicious Polish sausage at his market that contains Tart Cherries as well.
Its worth the trip from anywhere to come to Michigan's Gold Coast for the cherry festival in July, The Sleeping Bear Dunes National Lakeshore and to visit Ray's in the quiet little burg of Cedar (14 miles west of Traverse City) on the South Western shore of Lake Leelanau.
