re: Shrimp boil , always hard to peel

I bring back to a boil - and when the shell begins to separate from the shrimp, I cut the fire. BRING THE WATER TEMP DOWN. You can add ice, frozen lemon puree, whatever. It has to be lowered. 45 minutes is a long time for shrimp, but its cool if the water temp is low enough (under 160 I think?).

Also - Throw a stick of butter in there!
