Butter sauces are rich and flavorful sauces made primarily from butter. They are often used to enhance the taste of various dishes, including seafood, vegetables, and pasta. Common types of butter sauces include beurre blanc, a French sauce made with white wine and shallots, and beurre noisette, which is browned butter that adds a nutty flavor. These sauces are typically easy to prepare, requiring just a few ingredients. The key to a successful butter sauce is to control the heat, ensuring the butter melts smoothly without burning. Butter sauces can be customized with herbs, spices, or citrus for added depth and complexity.
