To date this year I've harvested 3 potato varieties.
La Ratte. This one is a yellowish-white fleshed fingerling. Great for frying or boiling. Just don't try to mash it. It has a delightful nutty flavor.
Dark Red Norland. The potato of my childhood. Red skinned, white fleshed. Mom used this one for everything but baking.
Purple Majesty. Purple skinned, purple fleshed. It's a beauty. Makes great fried potatoes. We like the flavor of this one.
