Braised Fish with Fennel and Tomato
This type of quick braising is similar to shallow poaching (page 210): An aromatic liquid is first simmered to allow the flavors to deepen, then simmered with fish, which takes on some of its character. Also, as with some poaching methods, the braising liquid becomes the sauce. Match the fish and aromatics wisely so as not to overwhelm one or the other. A fish such as salmon is easy to partner; its pronounced taste won’t be flagged by aggressive flavors, such as rosemary or curry powder. Milder-tasting fish, such as grouper, halibut, sea bass, and striped bass, require more subtle companions, like the fennel, tomatoes, and lemon in this recipe. All of these fish are moist and firm-fleshed, ideal for braising.
