WASHINGTON – A McDonald’s franchise owner from Maryland had a grand idea that will become a reality at 700 McDonald’s locations next week: Old Bay tartar sauce with Filet-O-Fish sandwiches.

The fast food giant and Old Bay maker McCormick & Co teamed up to offer the special combination for a limited time, The Baltimore Sun reports. Starting Feb. 16, the sandwich will be available at hundreds of locations in Maryland, Virginia, West Virginia, Delaware and D.C.

“We know that Old Bay is as popular as salt and pepper on our tables here in Baltimore,” Mark Furr, the franchisee who came up with the idea, told the Baltimore Sun. “McDonald’s is extremely excited to be able to deliver a true, local taste to our customers via our classic Filet-O-Fish sandwich with a special Old Bay tartar sauce.”
