re: How to do boiled shrimp.

Need a lot more salt/spice than for crawfish. Need enough water boiling so that the quantity of shrimp you add doesn't drop the temp below boiling, at least not for long at all. Don't lose boil if you can help it. Add ice during soak to cool water where the shrimp stop cooking... 160-180 is all you need to keep them warm. Other than that, you've got it.
