Prepare the dredging station by placing the flour in a bowl and season with sea salt and fresh cracked pepper, to taste.
Place the well-beaten eggs in a bowl and season with sea salt and fresh cracked pepper, to taste.
Place the panko crumbs in a bowl and season with sea salt and fresh cracked pepper, to taste.
Dredge the razor clams by lightly coating them in the seasoned flour, next, dip them in egg mixture, and lastly, dip them in the seasoned panko, making sure to coat evenly.
Set aside on a plate; repeat until all clams are dredged.
Place the plate of clams in the refrigerator for 20 minutes. Side Note: Don't skip this step because it helps ensure the panko will stay on the clams when cooking.
Meanwhile, make the tarter sauce by combining the ingredients in a small bowl; mix thoroughly. Taste and re-season if necessary. Place in the refrigerator to allow the flavors time to mingle.
Make the cocktail sauce by adding wasabi to the ketchup, to taste, until it's as spicy as you desire. Place in the refrigerator to allow the flavors time to mingle.
Cook the clams by heating half the oil and butter in a large skillet over medium-high heat.
Once the skillet is HOT, add the clams, making sure not to overcrowd the large skillet. Cook for 1-2 minutes on each side until golden brown, don't overcook or they will be tough & chewy.
Wipe out the large skillet, add more oil and butter to the large skillet then cook the remaining clams.
Place on a paper towel lined plate to drain excess grease, then serve immediately with fresh lemon wedges, cocktail sauce, and tartar sauce. Enjoy.
