We had half that big plaice last night - it was very nice - simply baked with the usual suspects (s&p, olive oil, butter) with a twist of orange and roasted veg.
It seemend to have more flavour than the smaller ones I have caught. I am too please with my recent purchase of a vaccum sealer - bought after the glut of Turbos from Alderney. Seems to keep the fish beautifully, I have also stopped washing the fish before freezing too.
Mmmmmmm!
