Beurre monté is French for “mounted butter.” It is an emulsion: butter whisked into a small hot-water or stock base, so the fat and water stay together as a smooth, shiny sauce.
It is related to monter au beurre, mounting a finished sauce with cold butter off the heat. Beurre monté is its own base, though: water first, then butter whisked in, ready to hold and spoon.
