I've never heard/seen anything called "partridge berries" before.
Hmm...they look like cranberries...
maybe something new?
Nope. They're cranberries!
Apropos of not much, we have in my neighborhood, a craft store called Cranberry Hill, which always struck me as somehow-off.
Cranberries grow in bogs, not on hills, dammit!
Bogs are upside-down hills, inverted hills, the opposite of hills!
You can always make an adult desert called Bachelor's Jam. A bunch of berries, fresh fruit etc mixed with sugar, in a ratio of 1 lb of fruit to 1 cup of sugar (adjust to taste, cranberries may need a bit more...) transfer to clean jars and top up with 80 proof liquor (brandy, rum, kirsch, vodka, Armagnac, whatever you think you'd like) and let sit for about 2 - 3 weeks. When it tastes good to you, you can eat it out of the jar or use it to top your ice cream, yogurt, whatever you want.
