For this recipe, I like to use unsalted butter. I want to be able to control the level of salt when the fish is cooked.
Make sure there is enough liquid (butter or lemon juice) to cover 2/3 up the side of the fish while cooking.
Finish this recipe with a touch ofFleur de Selor a touch ofsea salt. I think both of these two types of salt add something extra special to the fish.
Use room temperature butter for more even melting
Don’t let the butter get too hot – no bubbling or browning
Choose fillets of similar thickness for even cooking
Pat fish completely dry before poaching
Let fish come to room temperature before cooking
