Don't go far- at 225 or so the shrimp will only take 25-30 minutes. If you are ready to eat, got for it. Otherwise put them in the fridge immediately. We would recommend at least 2 hours, if not overnight, to cool before preparing the salad. Allow the peppers to continue to roast after the shrimp is pulled until they are softened. Put the papers in a paper bag, let them rest for a while, and then peel their skin. Let them rest in the fridge along with the shrimp.
