I did some kalbi cut beef ribs last week on my 380 at 450 with grillgrates. I did not get much of a sear on the meat. It had been marinated, so that may have been the problem. I plan on doing bacon wrapped shrimp tomorrow. The recipe (HeyGrillHey) calls for 450 for ~ 8 minutes turning over multiple times. Do I need to up the temp? Also, with the 380 open for 8 minutes, will it hold temp? I've only done a few cooks on the 380, so looking for tips. Thanks.
