Dredge the flounder in a small amount of flour.

In a separate bowl, mix the remaining ingredients (flour, salt, beer, oil, egg coloring, baking powder, pepper) until smooth, forming a batter.

Heat oil or shortening in a deep fryer to 350°F (175°C).

Dip the floured fish into the prepared batter, ensuring it is fully coated.

Carefully lower the battered fish into the hot oil.

Fry for 3 to 4 minutes, or until the fish is crisp and golden brown.

Remove the fish from the oil and place it on a wire rack or paper towels to drain excess oil.

Serve immediately.
