Strain the lump crab meat in a strainer. As it is straining, lightly pick through and separate the lumps to remove any shell or cartilage that may be mixed in. *Be gentle to keep the lumps in tact.
In a large mixing bowl, combine the mayonnaise, egg, Worcestershire sauce, Dijon mustard, lemon juice, hot sauce, Old Bay seasoning, cracker crumbs, and salt and pepper. Mix together until well combined.
Gently fold in the strained lump crab meat, taking care to keep the crab meat lumps in tact.
Form the crab cake mixture into 6 equally sized cakes. Then lightly coat the top and bottom of each cake with a thin even layer of panko breadcrumbs. *I recommend placing a thin, even layer of panko breadcrumbs in the bottom of a silicone ring egg mold, then gently pressing the crab cake mixture into the mold. Lightly coat the top of the crab cake with a thin layer of panko, and then carefully remove the silicone ring mold.
Place the crab cakes on a baking sheet and refrigerate for 15-20 minutes. This helps the ingredients come together and prevents the crab cakes from falling apart during cooking.
While the crab cakes are refrigerating, heat the griddle until it reaches about 375 degrees F.
Add about 3 tablespoons of butter and ¼ cup of your favorite cooking oil to the heated griddle surface and spread it around a bit with your spatula. Gently place the refrigerated crab cakes in the oil/butter and begin to shallow fry. *You can use your spatula or scraper to scrape the excess oil towards the crab cakes if needed. Allow the crab cakes to fry on the first side for about 5-7 minutes, or until light golden brown. Then, carefully flip the cakes to the second side and continue to cook an additional 4-5 minutes.
Transfer the crab cakes to a baking sheet and keep in the oven on warm while you are making the blender Hollandaise. Or alternatively, serve the crab cakes immediately with tartar sauce or your favorite toppings.
