Prepare Applebee's Dynamite Sauce according to recipe below. Set aside.
Cover a large plate with several layers of paper towels. Set aside.
Butterfly shrimp by cutting vertically down the back of the shrimp. Leave tails on.
Season shrimp with salt, pepper and seasoning salt.
Place panko crumbs in a shallow dish. Season with salt, pepper and seasoning salt to taste. Mix well.
Put flour in a second shallow dish.
In a small bowl, beat eggs and water together with a spoon or whisk.
Heat enough oil to deep fry the shrimp in a skillet to 350°F.
While oil is heating, dip prepared shrimp, 2 or 3 at a time, in the egg-water mixture.
Add shrimp to the flour. Toss to coat.
Dip again in egg-water mixture.
Toss shrimp in panko crumbs.
Repeat until all shrimp are coated.
Place shrimp, a few at a time, in the hot skillet. Fry until golden, about 3 minutes. You may have to turn the shrimp to evenly brown them.
Place cooked shrimp on a paper towel-covered plate to drain and continue frying until all shrimp are done. Keep shrimp warm while frying batches of shrimp.
Remove skillet from heat and carefully wipe out with a dry paper towel (alternately use a new skillet or a wok.)
Add teaspoon of oil and place over high heat.
When hot, add prepared Applebee's Dynamite Sauce. Simmer for 1 minute to thicken.
Add fried shrimp. Toss to coat fully and cook for 1 minute more.
Serve hot.
