In a medium size bowl combine eggs, Worcestershire sauce, lemon juice, Old Bay seasoning, parsley, mayo and mustard. Mix well.
Place crabmeat in a separate bowl and add your cubed bread, pour the wet mixture over the crabmeat and bread or breadcrumbs and then gently mix until the crabmeat and bread is covered in the egg mixture.
Work with your hands to create round balls of the mixture, then place in the refrigerator. Wait at least a half hour before frying the crab cakes.
Pour the oil in your frying pan and wait a few moments for the oil to be hot. Once the oil is ready gently place your crab cakes into the pan. Do not touch for several minutes.
Then gently flip the cakes over and wait a few minutes, then lower the temperature. Cakes should be cooked through in 4-5 minutes on each side.
