Beurre Monté: The Workhorse Sauce
At the French Laundry, we use an awful lot of butter without serving a lot of butter because of a method and substance called beurre monte--a way of infusing meats and fish with the flavor of butter. We cook in it, rest meats in it, make sauces with it. It's an extraordinary vehicle for both heat and flavor. Here's what beurre monte is: a few drops of water and chunks of butter whisked over a moderate heat to melt the butter and keep it emulsified, in one piece and creamy. Solid butter is an emulsification of butter fat, water, and milk solids; beurre monte is a way to manipulate the emulsification into liquid form.
