In cooking what is bearnaise?

Béarnaise sauce is a rich and flavorful French sauce made with clarified butter, egg yolks, white wine vinegar, tarragon, and shallots. It is traditionally served with grilled meats, especially steak.

To make béarnaise sauce, start by reducing white wine vinegar and shallots in a saucepan over low heat. When the liquid has reduced by about half, add the egg yolks and whisk constantly until the mixture has thickened and doubled in volume. Remove the saucepan from the heat and slowly whisk in the clarified butter. Season the sauce with salt, pepper, and tarragon.

Béarnaise sauce is best served immediately, as it can quickly separate if it is not kept warm. It is a versatile sauce that can be used with a variety of dishes, including fish, poultry, and vegetables.

Here are some tips for making béarnaise sauce:

* Use a stainless steel saucepan to avoid the sauce discoloring.

* Use clarified butter to prevent the sauce from becoming grainy.

* Whisk the egg yolks and butter constantly to ensure that the sauce does not curdle.

* Season the sauce with salt, pepper, and tarragon to taste.

* Serve the sauce immediately, as it can quickly separate if it is not kept warm.
