Huckleberry

A wild, blue-black berry that closely resembles the blueberry. The huckleberry, however, has 10 small hard seeds in the center that give it a crunch texture, whereas the blueberry has many tiny soft seeds that are barely noticeable. Also, the huckleberry has a thicker skin and is slightly less sweet and more astringent. Huckleberries are not cultivated commercially, so you will have to find them in the wild. The entire fruit is edible, no need to remove the seeds.
