The Blue Adirondacks are well-known for their blue/purple flesh and dark purple skin, and they hold their color during cooking to produce colorful plates. Generally, blue potatoes have a nutty, earthy flavor with a slightly sweet taste. They are similar to russet potatoes in terms of starch content and flavor but tend to be less starchy and more moist. These blue potatoes in particular compare well with Yukon Golds in terms of flavor profile.
