Fries are somewhat the national dish of Belgium. You'll never hear a Belgian call them “french fries”, not even when speaking in English. There’s a lot of controversy around who invented fried potatoes, but I promise you – Belgians perfected them. Once you eat fries in Belgium, they’ll never taste as good anywhere else. The secret to the perfect Belgian fry is two-fold. First, the potato itself must be a soft variety, but, most importantly, the freshly cut potatoes must be fried twice: First at a lower temperature to cook the inside to a soft, fluffy consistency; and second, quickly at a higher temperature to cook the outside to crispy perfection.
