I work at a very popular Baltimore crab house/restaurant that has a little trick that none of our customers know about....they pre-steam the crabs. We usually get a few bushels in each day. They're sorted, and then immediately steamed. Sometimes those crab that are steamed sit for a day before they're actually sold cuz we steam so many crabs at once. Funny thing is a lot of our customers rave about how good our crabs taste! Little do they know the crabs they're eating were steamed yesterday, sat in a cooler for 24 hours and then were flash re-steamed for their enjoyment.
They're simply seasoned with JO, but besides that, I believe maybe the crabs sitting in their own juices actually enhances their flavor as I too agree that they are delicious! If the customers actually knew they were re-steamed I'm sure they would be appalled but what you don't know can't hurt you! If only people REALLY knew what goes on behind the scenes where they eat!
....And on a side note, don't be an a$$ when you go out to eat because what goes around comes around. It's truly amazing how some people act when they go out to eat.
There are a lot of unkind words I can use but really it's just embarassing sometimes.
