Can you purchase a lobster in the morning, have it cut up in pieces by the fish monger, and then cook it later that day....how best would one keep it?
Just keep it cold in the fridge
Lobsters are generally sold live. Not sure I'd want to cook an already dead lobster. I normally store fish in the fridge by rewrapping it in waxed paper and setting the package atop a bowl of ice water. I suppose that would work for your lobster pieces as well.
Absolutely agree with ChefOno on this. Crustaceons begin to decay as soon as they are dead. But a live lobster will survive on ice for at least four hours. How you dispatch the lobster is up to you. And I also agree on the importance of the shell. The French sauce Homard L'Americane is based on incorporating the shell.
Thanks so much. I think I can do this.
You can also hold a live Lobster overnight in a ice chest lined with wet newspaper..(preferably in a chilled salted water to moisten the paper)on top and bottom of the bug. And a few ice packs or cubes to keep the temp down below 55 or so to slow it's metabolism.
