Step 1

In a large Dutch oven, heat 3 inches of oil. If you're using an electric tabletop fryer, fill the unit to its MAX line.

Step 2

Preheat the oil to 350 degrees over medium-high heat, using a deep-frying thermometer to check the temperature. When the oil reaches 350 degrees, reduce the heat to medium-low.

Step 3

Meanwhile, pat the fish dry with a paper towel and cut the fish into four 3-ounce portions. If you like, you can create a diamond shape by trimming off the sides. Set aside.

Step 4

In a medium-sized bowl, combine the flour, corn flour, cornstarch, MSG, paprika, garlic salt, onion powder, white pepper, baking powder, and baking soda.

Step 5

When the oil is preheated and ready to go, add the club soda to the dry batter mixture. Stir until just combined, taking care not to overmix. It's okay if there are a few clumps in the batter.

Step 6

Dip the fish into the batter, making sure it's coated on all sides. Gently drop the battered fish into the oil and fry for 3 to 5 minutes, until the exterior is golden brown.

Step 7

Remove the fish to a paper towel-lined plate to remove excess grease. Season the fish with kosher salt, to taste.

Step 8

Serve immediately.
