My granny used to cook fish on a plate. It’s a great way to make perfectly steamed fish without overcooking it. Any white fish fillets will do; Snapper, Gurnard, Terakihi, to mention some New Zealand fish. In Scotland I made this with Haddock. Granny preferred Lemon Sole. This recipe is really only suitable for cooking for one or two. Any more than that and the fish won’t fit on the plate!
