I poached some frozen salmon fillets and when they were cooked they had a milky white scum on their surfaces. What is this? It did not look very nice. Is there a way of preventing this? Anon

Thank you for your question. The white scum on the salmon is called white albumen and it is entirely naturally occurring dead proteins. To prevent this from coming on your fish, make sure that you wash it with cold water and also make sure that the fish is as fresh as possible prevent the white scum from appearing. I hope this helps.
