beurre blanc
High in fat (butter-based), providing minimal nutrients beyond calories; used in small serving portions as a sauce rather than as a primary ingredient.
About
Beurre blanc (French: "white butter") is a classic French emulsified sauce composed of a reduction of white wine and shallots mounted with cold butter. The sauce is prepared by reducing white wine or vinegar with minced shallots to concentrate their flavors, then whisking in cold butter piece by piece to create a creamy, light emulsion. The result is a pale, glossy sauce with a silky texture that relies on the emulsification of fat and liquid rather than a roux or cream base. The delicate nature of the sauce requires careful temperature control to maintain the emulsion without breaking or becoming greasy.
Culinary Uses
Beurre blanc is a foundational sauce in French haute cuisine, traditionally served with poached or grilled fish, seafood, and delicate white meats. The sauce complements steamed vegetables and is frequently offered alongside eggs Benedict variations and contemporary preparations. Its neutral, buttery flavor profile allows it to enhance rather than mask the principal ingredient. Modern chefs create variations by infusing the reduction with herbs, citrus, saffron, or other flavorings, and the sauce serves as the base for numerous derivative sauces (beurre rouge with red wine, beurre noisette with brown butter).
