Little more than piles of shredded potatoes, what separates superlative hash browns from the merely adequate hash browns all comes down to texture. Shatteringly crisp on the outside yet tender, even borderline creamy on the inside, it's a fine balance that's difficult to strike. Using a waffle iron instead of a standard frying pan maximizes the surface contact for a far more satisfying crunchy crust, while the enclosure allows the spuds to essentially steam from within, ensuring perfectly tender bites through and through.
