Storage: Leftover poached salmon can be stored in an airtight container in the refrigerator for up to 2 days. It is excellent cold in sandwiches or salads.
Substitutions: You can add lemon slices, dill, or bay leaves to the poaching water for extra flavor. For the tuna, sesame seeds or soy sauce make a great topping.
Tips: Ensure the water is only simmering, not boiling vigorously, to keep the salmon tender. Adjust poaching time slightly based on the thickness of your fillets.
Variations: Serve the tuna with a spicy mayo or ponzu sauce for an Asian-inspired twist.
