Poached fish is a cooking method where fish is gently simmered in a flavorful liquid, such as water, broth, or wine. This technique helps to keep the fish moist and tender while allowing it to absorb the flavors of the poaching liquid. Common types of fish used for poaching include salmon, cod, and tilapia. To poach fish, the liquid is heated to a low temperature, just below boiling, and the fish is added. It typically cooks for about 10 to 15 minutes, depending on the thickness of the fillet. Poached fish can be served with various sauces or garnishes, making it a versatile dish.
