Pointless photo of the day:

High Bush-cranberries are edible but aren't the cranberries you have with Thanksgiving turkey (those are Bog Cranberries). Straight off of the bush they are very sour, but if you cook them with sugar and strain them to remove the pits, they make a cranberry-like syrup that gives the plant its name.

A relative, Low Bush-cranberry (Both are Viburnums. High Bush-cranberry, aka Pembina, is V. trilobum. Low Bush-cranberry is V. edule), also has edible berries, but since its strategy to spread its seeds is for the fruit to smell somewhat like a carcass when it's ripe (most animals -- even herbivores -- will take advantage of the energy to be found in a rotting dead animal), your house will smell uncomfortably like old sweatsocks while you're cooking the syrup down.

Not my choice, as you can imagine.

The plant in the picture is nursery stock, but the wild ones look very similar.
