Béarnaise sauce (/bɛrˈneɪz/; French: [be.aʁ.nɛz] ⓘ) is a sauce made of clarified butter, egg yolk, white wine vinegar, and herbs. It is regarded as a "child" of hollandaise sauce. The difference is in the flavoring: béarnaise uses shallot, black pepper, and tarragon, while hollandaise uses white pepper or a pinch of cayenne.
The sauce's name derives from the province of Béarn, France. It is a traditional sauce for steak.
