Béarnaise Sauce is a classic French sauce known for its rich, buttery flavor with a hint of tarragon. This luxurious sauce is perfect for enhancing steaks, fish, or vegetables. Made with a reduction of wine and vinegar, then emulsified with egg yolks and butter, it's a sophisticated addition to any gourmet meal. While it requires some skill to prepare, the result is a velvety smooth sauce that elevates any dish it accompanies.
