Goldrush, Snowden and Atlantic are varieties of potatoes. Goldrush is a variety of russet potatoes, which are high in starch. Snowden and Atlantic are varieties of white round potatoes. They are lower in starch than russets and hold together better when cooked.
Due to medium starch content, Snowden and Atlantic potatoes hold their shape when fried, which is the reason for their wide use in making potato chips. On the other hand, russet varieties, such as the Goldrush potato, are high in starch, which creates a fluffier and light potato texture when cooked. Russet potatoes are ideal for making baked potatoes and fluffy mashed potatoes.
