In a medium bowl, toss cheese and flour together. Heat a medium nonstick skillet over medium-low heat. Sprinkle 1 1/2 tablespoons of the cheese mixture into the pan to form a circle about 4 inches in diameter.
Cook until the cheese is somewhat melted but not firm, about 2 minutes. Using a spatula, turn the cheese over, and cook until it is visibly firm and just taking on a little color, 30 seconds to 1 minute.
Transfer the frico from the pan to a paper towel, and hold it in the palm of your hand. Press an offset spatula down the middle to form a taco shape. Transfer to paper towels to cool. Repeat with remaining cheese. Store at room temperature in an airtight container for 2 to 3 days.
