Ingredients

• 2 cups balsamic vinegar
• 8 cups canola oil, peanut oil or liquid shortening, for frying
• 3 pounds russet potatoes, peeled and cut into fries
• Kosher salt and freshly ground pepper
• 12 ounces gouda cheese, shredded (about 4 cups)
• Pinch of red pepper flakes

Instructions

1. Make the balsamic glaze: Bring the vinegar to a simmer in a saucepan over medium-high heat. Simmer until syrupy and reduced to about 1/2 cup, 8 to 10 minutes; keep warm or at room temperature.
2. Make the fries: Heat the oil in a heavy-bottomed pot or Dutch oven over medium heat until a deep-fryer thermometer registers 220 degrees F. Working in batches, add the potatoes and fry until slightly colored but still pale, about 5 minutes. Transfer to a baking sheet using a large slotted spoon; let cool.
3. Increase the heat to bring the oil temperature to 350 degrees F. Working in batches, return the fries to the hot oil and fry until golden brown, 8 to 10 minutes. Transfer to a paper towel-lined baking sheet using a large slotted spoon. Season immediately with salt and pepper.
4. Preheat the broiler. Transfer the fries to a heatproof platter or baking sheet. Sprinkle with the cheese and broil until it melts, about 2 minutes. Drizzle with some of the balsamic glaze and sprinkle with the red pepper flakes. Photograph by Kat Teutsch
