Why food browns — and why yours sometimes doesn’t
Grey chicken is not a seasoning problem.
Three shades, one narrow window
Browning is a chemical reaction, not just a colour. Below roughly 140 °C almost nothing happens; above it, proteins and sugars on the surface start rearranging into hundreds of new compounds that taste of roast, toast and meat. Push further and those same compounds carbonise into bitterness.
Worth remembering The window between pale and burnt is smaller than it looks, and it opens fast.
Water is the reason it stays grey
Wet food cannot get past 100 °C, because every joule of heat goes into boiling water off rather than raising the temperature. Until the surface is genuinely dry, it is being steamed — no matter how hot the pan is underneath. This is the entire explanation for grey chicken.
Worth remembering Nothing browns while it is still wet. Dry the surface before it meets the pan.
A crowded pan is a cold pan
Food arrives cold and full of water. Put in too much at once and it steals more heat than the burner can replace, the pan drops below the browning threshold, and the water everything releases has nowhere to go. Two batches in a hot pan beat one batch in a crowded one every time — and it is not even slower, because a stewing pan takes forever.
Worth remembering If you can’t see pan between the pieces, it is going to steam.
Two different browns
Meat and bread brown by the Maillard reaction, which needs both protein and sugar. Plain sugar browns on its own, at a higher temperature, and that is caramelization. Onions do both at once, which is why they taste so much more complicated than either. Knowing which one you are chasing tells you whether to reach for heat or for time.
Worth remembering Maillard needs protein and sugar. Caramel needs only sugar — and more heat.
