Any purported Maryland or Baltimore crab cake recipe that contains Dijon mustard or Worcestershire sauce is about as authentic as Omaha Style crab cakes. Don't be sold a bill of goods! This is the real deal. This recipe has stood the test of time at any number of Baltimore eateries. Its roots are from the Rennert Hotel (long before Old Bay was marketed as a packaged spice blend - restaurant chefs made their own Maryland-style seafood spice blends before the 1940's). This version comes from Walker - Hasslinger's famed Charles Street restaurant during the early 1950's (my grandmother worked there as a line cook for many years). They used a local spice blend called "J.O.," which is still produced, but is not available outside of Baltimore. Their crab cake, like any true Baltimore crab cake, was either broiled or pan-fried in clarified butter, and NEVER deep fried.
