Béarnaise sauce belongs to the esteemed family of emulsified sauces, sharing kinship with hollandaise. This simply means it's a luxurious blend where fat (usually butter) and water (typically vinegar or lemon juice) are held together by egg yolks. In the case of béarnaise, the magic lies in the addition of fresh tarragon, infusing the sauce with a unique, herbaceous aroma that perfectly complements grilled meats.

Studies have shown that the right sauce can significantly enhance the enjoyment of a meal. A 2010 study that was published in the Journal of Food Science found that customers reported more flavor and overall satisfaction when a steak was given with a properly matched sauce. Béarnaise sauce, with its rich, buttery base and bright tarragon notes, exemplifies this perfectly.
