If you want the classic, cloud-like interior that caves under the weight of butter, you need a Russet Burbank. This is the potato that launched a thousand loaded skins. It’s the ugly duckling of the spud world—bumpy, brown, and covered in weird eyes—but inside, it’s a pillow of pure starch.
Here’s the surprising science: Russets have a lot of starch and very little sugar. When you bake them, the starch granules swell and burst, creating that signature fluffy texture. Don’t be fooled by the “baking potato” label at the store—that’s almost always a Russet, but not all Russets are created equal. Look for ones that feel heavy for their size and have no green spots (that’s poisonous chlorophyll, and it tastes like regret).
A fun fact: these potatoes were invented by a man named Luther Burbank in the 1870s, who bred a plant that produced 17 different types of potatoes. He was a mad scientist of the soil, and we are forever grateful. Just remember: you can’t mash a Russet without it turning into glue, so save them strictly for baking.
