BÉARNAISE SAUCE
Béarnaise is the ultimate creamy accompaniment to steak.
Find your tenderloin a bit lacking in fat and flavor? Never
fear, béarnaise sauce will come to the rescue! If you’ve
already learned how to make Foolproof Hollandaise Sauce
(here), then congratulations—you know how to make
foolproof béarnaise as well. The two are nearly identical, the
only difference being the liquid element. While hollandaise
is an emulsion of butterfat, egg yolks, and lemon juice,
béarnaise replaces the lemon juice with a tarragon-and-
shallot-scented vinegar-and-white-wine reduction.
Everything else is exactly the same.
