Herb Saint is a New Orleans‑specific herb blend that features anise‑flavored herbs like laor, reflecting the city's French‑Creole roots and love of aromatic, slightly licorice‑like flavors. The cream sauce combines this local herb with the holy trinity—celery, onion, and poblano—creating a bridge between classic Cajun foundations and modern fine‑dining techniques.

In traditional Southern cooking, cream sauces often rely on butter, garlic, and herbs like thyme or parsley. The New Orleans version swaps those for Herb Saint and incorporates the holy trinity, giving it a distinctive peppery and anise note that you won’t find in other Southern states.

At upscale New Orleans establishments like Emeralds, the sauce is drizzled over a simply seared or pan‑roasted fish such as Mississippi trout, allowing the delicate flesh to shine while the sauce adds richness and a bright herbal finish. It is often paired with seasonal vegetables or a light rice pilaf.

This dish appears on tasting menus for special events such as Mardi Mardi celebrations, holiday tasting menus, and chef’s tasting tables, where chefs showcase local ingredients like Gulf trout alongside signature New Orleans flavors.

The sauce’s uniqueness lies in the use of Herb Saint, an anise‑laden herb blend rarely found outside the city, combined with the holy trinity and a rich cream base. This creates a flavor profile that is simultaneously sweet, herbal, and slightly licorice‑like, setting it apart from typical Southern butter sauces.

Common errors include over‑seasoning the fish before searing, allowing the cream to boil (which causes curdling), and not reducing the wine enough, which can leave a harsh alcohol taste. Also, failing to press the trout skin at the start can result in a soggy skin.

Herb Saint paste concentrates the anise flavor and provides a consistent texture that blends smoothly into the cream, whereas fresh anise can be too fibrous and overpowering. The paste also allows chefs to control the intensity more precisely.

Yes, you can prepare the sauce up to the point before adding the butter‑shallot mixture. Cool it quickly, store in an airtight container in the refrigerator for up to 2 days, and reheat gently over low heat, finishing with the butter‑shallot blend just before serving.

The sauce should be glossy, smooth, and thick enough to coat the back of a spoon without clinging in pools. The color is a pale ivory with a faint green hue from the Herb Saint, and it should have a velvety mouthfeel.

The trout is done when the flesh flakes easily with a fork and is opaque throughout, typically after an internal temperature of 145 °F (63 °C). The skin should be crisp and release from the pan without resistance.
