4 ounces sharp white cheddar or your favorite cheese, grated (about 2 cups)
1 teaspoon all-purpose flour (optional)
In a medium bowl, toss together cheese and flour. Heat a large nonstick skillet over medium-low heat. Sprinkle about 1 1/2 tablespoons cheese mixture into skillet to form a 4-inch round.
Cook until cheese is starting to melt and become firm, 1 1/2 to 2 minutes. Using a small offset spatula, turn; continue cooking until it is firm and slightly golden, 15 to 30 seconds more. If skillet gets too hot and frico begin to color too quickly, remove from heat for several minutes before proceeding.
