Lay's Chesapeake Bay Crab Spice Chips (2018-2019, 2021): Part of the "Taste of America" line, which featured regional dish-inspired flavors, these potato chips were seasoned with an Old Bay-style spice blend, and sold solely in the Mid-Atlantic region before getting a brief national run in 2021

I crave the crab.
I'd argue crab chips are one of the staple chip flavors in Maryland and surrounding regions, much in the same way All Dressed chips are ubiquitous in Canada.
Maryland-area McDonalds also briefly served filet-o-fishes with old bay tartar sauce. It was delicious and I miss it dearly every day.
