Béarnaise sauce is a classic French sauce made from clarified butter, egg yolks, and flavored with herbs. It is similar to Hollandaise sauce but includes the addition of shallots, tarragon, and vinegar, giving it a distinct taste. This sauce is often served with grilled meats, particularly steak, enhancing the dish with its rich and creamy texture. The preparation of Béarnaise sauce involves emulsifying the egg yolks with the melted butter while incorporating the herb-infused vinegar reduction. It is typically served warm and is a popular choice in French cuisine, celebrated for its versatility and flavor.
