Wow, the combination of the fennel, white wine and dill make this a fantastic, flavorful stew. The fish is simmered slowly in a combination of white wine and water, on a low heat which helps retain its tenderness. Sliced raw fennel adds a sweet licorice flavor, but if you sauté, roast or grill it, it softens the licorice flavor. Served with hearty greens, this is an easy weeknight meal. Pick a firm white fish with a delicate flavor. I tried wild caught blue catfish which is delicious. Other fish options would be haddock, flounder, tilapia or cod.
