Huckleberries, sometimes called "purple gold", are small, round, wild berries that are red, blue, or black in color, closely related to blueberries but typically more tart with larger seeds. Primarily found in the Pacific Northwest and Rocky Mountain regions, they grow in the wild on shrubs rather than being cultivated, making them a sought-after, intense-flavored ingredient for jams, pies, sauces, and cake pops.
