[EX Q]: I have a packet of fresh tilapia filets from the grocer, and I'm planning to broil them with BBQ sauce. How long should they stay under the heat and how far should they be from the heating elements? My broiler is the "under-the-oven" kind which re-uses the gas flame that pre-heats the main oven.Edit: Are there any additional preparation steps I should be aware of? I'm a novice when it comes to cooking fish.
