Prep time: 10 minutes
In a deep-fryer or large pot fitted with a thermometer, heat the oil to 350°F/176.6°C.
Fry the fries in batches as needed (3 ounces per serving), about 5 minutes per batch. Immediately sprinkle generously with salt and toss with the shichimi and nori (1/4 teaspoon of each per serving). Spoon the kimchi (1/4 cup per serving) over the top and drizzle with the cheese sauce (1/4 cup per serving), or serve with the cheese sauce on the side. Top with the green onions.
Cheddar Cheese Sauce: Heat the milk in a medium saucepan over medium heat to just below a simmer. When bubbles are just beginning to come to the surface remove from the heat.
Melt the butter in a small stockpot over medium heat and whisk in the flour. Continue to whisk until the mixture is light brown, about 3 minutes.
Slowly, while whisking, add the milk. Whisk continuously until the sauce is silky and thickened. Add the cheese and whisk until melted and smooth.
