Created in 1836 at the Pavillon Henri IV restaurant in Saint-Germain-en-Laye, béarnaise takes its name from the Béarn region of southwestern France — birthplace of Henri IV. The chef Collinet is credited. Despite the regional name, béarnaise was a Parisian restaurant invention — the Béarn connection is through royal association rather than agricultural origin. The tarragon-shallot reduction (the gastrique) is the defining technique; it is what separates béarnaise from every other hollandaise derivative. · Sauce Making
Tarragon is béarnaise's soul, and understanding why reveals the sauce's intelligence. Tarragon's primary aromatic compound — estragole — shares anise register with fennel and star anise but is warmer, more herbaceous, less aggressive. Against beef, this bridge compound performs a specific function: it sits between the fat of the butter and the iron-rich depth of the meat, resolving a flavour tension that few other herbs can. As Segnit observes, tarragon and chicken is almost reflexive — the herb's profile seems shaped to complete white-fleshed protein. The shallot in the gastrique adds a gentler allium note than onion, contributing sulphur compounds that bond with butter fat to create depth without aggression. Black pepper in the reduction adds piperine that opens the palate, allowing the butter's fat-carried aromatics to register with greater intensity.
— **Flat, vinegary sauce:** The gastrique was not reduced sufficiently. The vinegar's sharpness was never concentrated enough to develop the aromatic depth that makes béarnaise distinctive. This cannot be corrected in the finished sauce. — **Sauce breaks:** Identical to hollandaise — oil too rapid, heat too high, yolks over-developed. Rescue with a fresh yolk. — **No tarragon character:** Dried tarragon was used, or fresh tarragon was added to the reduction rather than reserved for the finish. The volatile compounds that make tarragon taste of itself are destroyed by sustained heat. — **Granular, cooked-egg texture:** The yolks scrambled. Heat too high in the bain-marie. The bowl was touching the water. Cannot be recovered.
