This is the guts, innards and fat found inside of the crab shell. I’m not really sure what the proper term for this yellow soup-y thing is, but the best name I found on the internet is “mustard”. It was served cold and very tasty! Use the sourdough bread to mop up this delicious yellow, fatty soup!
Swan Oyster Depot, San Francisco

Love this place! This was my first time here, but I’d definitely go back and even brave the long line again.
