Make the egg wash by mixing one egg with 2 Tbsp water. (If preferred, substitute with melted butter or dairy free margarine.) Brush the egg wash over the tops of the dough.
You may use 1 tsp. Old Bay seasoning in place of the paprika, pepper and cinnamon.
*For an egg-free version, use 6 Tbsp aquafaba.
Add some lemon juice to a half cup of mayonnaise and spread a dab on the crab cakes for added flavor.
