For a richer sauce, substitute heavy cream for 1/2 cup of the chicken broth. To prevent the salmon from overcooking, use an instant-read thermometer. The salmon is done when it reaches an internal temperature of 145°F (63°C). The poaching liquid can be made ahead of time and stored in the refrigerator for up to 24 hours. This can save time when preparing the dish. Serve with a side of steamed asparagus, quinoa, or a simple green salad for a complete and balanced meal.
