**Merluzzo Giallo con Crescione alla Mostarda all'Ancienne e Asparagi Verdi**

Merluzzo Giallo con Crescione alla Mostarda all'Ancienne e Asparagi Verdi is a contemporary French-Italian seafood dish that showcases the delicate flavor of yellow cod (merluzzo giallo) against a trio of spring accompaniments. The dish is most notably served at Le Bouillon in Rouen, France, where it has been highlighted by the food guide *Where The Foodies Go* as a standout example of modern bistro cooking.

The dish centers on a fillet of yellow cod, prized for its firm, flaky texture and mild, slightly sweet flavor. The fish is typically pan-seared to achieve a golden crust while maintaining a moist interior. It is paired with watercress (crescione) that has been lightly dressed or wilted, providing a peppery counterpoint. The defining element is the *mostarda all'ancienne*—an old-fashioned, coarse-grained mustard sauce that adds piquancy and a creamy, tangy richness. Green asparagus (asparagi verdi), often blanched or grilled, completes the plate with a vegetal sweetness and tender crunch.

A great version of this dish is distinguished by the quality of the cod, which should be sustainably sourced and cooked precisely to avoid dryness. The mustard sauce must be balanced—assertive but not overpowering—and the watercress should retain its fresh bite. Regional variations might substitute local greens like dandelion or nettles for the watercress, or use a milder Dijon mustard in place of the *ancienne* style. At Le Bouillon in Rouen, the dish reflects the chef’s commitment to seasonal, market-driven ingredients, elevating a simple fish preparation into a refined yet rustic plate that honors both Norman and Italian culinary traditions.
