How to Make It
Preheat the oven to 450°. Divide the cooked tater tots in 1 large or 4 small ovenproof baking dishes and arrange on a baking sheet.
In a medium saucepan, melt the butter. Add 1 cup of the kimchi and the flour and cook over moderate heat, stirring, until the kimchi is evenly coated in the flour, about 2 minutes. Stir in the milk and bring to a simmer. Cook until thickened, about 2 minutes. Season with salt. Spoon the kimchi gravy over the tater tots, then top with the cheese. Bake until the cheese melts, about 5 minutes. Top with the chile peppers and remaining ½ cup kimchi and garnish with chopped cilantro. Serve hot.
