Rescues · TO SEAR
The crust tears off and stays in the pan when turned.
Why it happens
Turned too early. The bond between food and metal breaks on its own once the crust has set; before that, the food is still gripping.
Recovering it
A pale sear can be pushed further — return it to a hotter, emptier pan. A burnt one cannot: the bitter compounds are not going anywhere, and the honest move is to cut the blackened surface away or start again. If the pan collapsed and the food has begun to steam, take everything out, let the pan get properly hot again, and return the food in batches. Whatever happened, the browned residue stuck to the base is worth deglazing into a sauce — that is the flavour you were trying to make.
The mechanism
Above roughly 140-165°C, amino acids and sugars on a dry surface react together — the Maillard reaction — producing hundreds of new aromatic compounds that did not exist in the raw ingredient. Water boils away at 100°C and cannot get hotter, so a wet surface is held at 100°C until it dries: every drop of surface moisture is time spent steaming instead of browning. This is why the two requirements are a dry surface and a pan hot enough to stay hot when cold food hits it. Searing does not seal in juices — that idea was tested and disproved long ago, and a seared piece of meat loses marginally more moisture, not less. What it buys is flavour, which is reason enough.
