The chowder can be refrigerated for up to 1 day. Rewarm over moderately low heat.
To remove the tail meat from a lobster in one piece, snap off the flipper at the end of the tail. Then place the tail on its side and press gently on it with the heel of your hand until you feel the shell crack; don't push too hard or you'll mangle the meat. You can also use kitchen shears to slice along either side of the soft underside of the tail. For both methods, put the tail on a kitchen towel and pull away the sides of the shell to release the meat.
