What causes potatoes to have brown centers or a hole inside? “Hollowheart” is a discoloured cavity in the centre of an otherwise healthy potato.

Why are my potatoes not browning?
A: This sure sounds a lot like potatoes that have been stored too long, in too cold of an environment before cooking. When potatoes are held below 41°F for too long a period, the starches convert to sugar and it changes the cooking chemistry.
Why should I Soak potatoes in water before frying?
The soaking, Mr. Nasr said, is the secret to the crisp texture of the fries. It draws out the starch, making them more rigid and less likely to stick together. The cooks fry them twice, first blanching them until slightly limp in peanut oil heated to 325 degrees, and again in 375-degree oil to crisp and brown them.
