Stored in a sealed container the Maryland Crab Cakes will keep well for up to 4 days in the refrigerator. They can be enjoyed cold or reheated in the oven or briefly in a microwave. Freeze the baked or fried crab cakes for up to 3 months by wrapping each individually in plastic wrap, and then place in an airtight plastic bag or another container. A layer of aluminum foil around the container will help to keep them even fresher.
