Deglazing

Deglazing (French déglacer) is a culinary technique in which liquid is poured into a hot pan where meat or vegetables have just been fried, to dissolve and gather from its bottom the browned, stuck-on residues. These residues, which the French call fond, are a concentrated source of flavour.

During frying a ruddy, in places scorched “crust” of caramelised juices and particles of the product forms on the bottom of the vessel — the result of the Maillard reaction and caramelisation. To throw it away would be a crime against flavour. So a little liquid is poured into the hot pan — wine, stock, cognac, or even water — and, vigorously scraping the bottom with a spatula, these aromatic residues are dissolved in the liquid. It instantly absorbs all that deep, rich flavour, becoming the base for a wonderful sauce or gravy. Then this liquid is usually reduced, and butter, cream, or spices are added — and in a matter of minutes from the “waste” of frying a refined sauce arises. Deglazing is a simple but ingenious technique that embodies the thrift and ingenuity of the cook, turning what seemed like scorched residue into the quintessence of a dish's flavour.
