Marbling alone does not split stew from grill. Heat was moderate for too long, or the piece started wet and spent ages steaming. Sear hotter and shorter, or use a two-stage method for thickness.

People credit the butcher for a great grilled dinner and blame the cook for a bad one — which is fair, because grill skill changes the chemistry the diner actually tastes: browned crust aromatics, rendered fat, and how much water is still trapped in the muscle. Technique is not decoration on top of a good cut. It is the difference between Maillard perfume and grey steamed protein, between juice on the board and juice in the mouth.

The Maillard reaction is a web of browning chemistry between amino acids and reducing sugars that accelerates at high surface temperatures when water activity at the crust is low. A wet steak steams first; steam caps the temperature near 100 °C and blocks deep browning. Patting dry, salting early enough to dissolve and reabsorb (or just before the pan), and using a properly preheated grate or plancha are not chef vanity — they are how you let browning chemistry run.

Grilling delivers intense radiative and conductive heat to the surface while the centre lags. That gradient is useful: you can build crust before the interior overshoots — if the piece is not absurdly thick without a cooler zone strategy. Two-zone fires, reverse sear and oven-finish methods exist because protein denaturation and moisture loss climb with internal temperature. Skill is choosing where the energy comes from at each stage.
