Note - I didn't use the cedar plank. I wrapped the fish in foil and put it on the grill. We had this out at the farm one night. Norm loved it!

Unlike a traditional pan-seared filet that relies on direct contact with metal to develop a crust, cooking delicate white fish on untreated cedar introduces indirect wood-smoke aromatics that subtly perfume the flesh while it bakes. Preparing lean fish like tilapia requires careful attention to thermal thresholds, because moisture leaves the muscle fibers rapidly once proteins tighten past 140 degrees Fahrenheit. Understanding how protein denaturing manifests physically prevents the common error of overcooking, which leaves the fish dry and chalky.
Visual and tactile cues remain the most reliable indicators of fish doneness when kitchen timers are merely estimates. Tilapia naturally separates into distinct flakes along the natural muscle seams, known as myotomes, when the internal collagen breaks down adequately. Inserting the tip of a paring knife or a fork tines gently into the thickest part of the filet should reveal opaque, slightly matte flesh that parts with minimal resistance. If the center still exhibits a translucent, glossy sheen, return the pan to the oven for another two minutes before reassessing.
