The secret is definitely in the crabmeat from the Md blue crab. No other crab is as sweet. I am fortunate to be able to get my off the dock fresh caught and picked that day. I use backfin and claw mixed together. No filler, i.e. Bread, cracker meal, etc. and no baking as it dries them out. Broil quickly about 4 to 5 minutes each side, but not to close to the broiler.
To two pounds of meat (1 pound backfin, one pound claw)Mix 3/4 cup thick mayo, 1/4 cup sour cream, 2 tablespoons whole grain mustard, an egg, and very very little old bay. You want to taste the crabmeat, not the old bay. Add mixture to crabmeat. Gently coat the meat until wet. Sometimes, my mixture gets too wet and to my absolute horror, I am forced to use just a tiny bit of cracker meal to be able to form the cakes. Form into crabcakes and broil!
Yes I live in MD and in the summer, by the water.
