Keeping the juices in

i know when braaing a fish if you leave it a minute to long on the coals it ends up drying out so quickly and thats not cool if you have a nice galjoen on the braai!
So no matter what the fish, put a light glaze of mayo on both sides of the meat. This will keep your fish from ever drying out during the cooking process and it also gives it a nice taste.
I do the same thing with melted butter sometimes when I just want to slap some hotties on the grill without getting out the cast iron pan.
Even simpler is to just use a type of oil spray, preferably olive oil based. I pretty much will use the oil spray on any type of non-fatty meat on the grill, including skinless chicken, sirloin steak, pork tenderloin, etc.

What's the best way to do roman? I bake most of my fish in the oven, but they seem to dry out helluva fast

My favorite way of doing tail is to just seal your fish in tinfoil with lemon juice, butter, fish spice etc and put it onto the fire closed. Then open it for the last 5 min before it is ready. It keeps all the juices in and my friends always seem to finish the fish. I always try take the smallest tail home and do just the fillet in the foil.
