If baking: Preheat oven to 350 degrees and line a baking sheet with parchment paper.
In a medium bowl, combine mayonnaise, egg, mustard, Worcestershire Sauce and crushed crackers. Gently fold the crab meat into the mixture. You want it thoroughly combined without pulling the crabmeat apart too much. Cover the bowl and let it rest in the fridge for an hour. You can also do this a night before.
When ready to bake or pan fry, using a large scoop or ⅓ cup measure to maintain equal sizes, gently make cakes out of the crab mixture. For appetizer portions, use approximately 2 tablespoons per crab cake.
Pan fry on a medium high heat with a good amount of oil in your pan to prevent sticking, or place on a lined baking sheet and bake for 35-40 minutes or 25-30 minutes for the appetizer sized portions. They will be browned nicely on both sides when done (without flipping them).
Serve with lemon wedges and Quick Tartar Sauce made by combining remaining mayonnaise and pickle relish.
