This evening I decided to make a nice fish pie. I did my usual recipe search on the BBC food website and found many a recipe. I sort of created an amalgam of two of the recipes as described below:
A couple of fish fillets (I used cod, but I think you could use other things like Haddock)
Half an onion
Stick of celery
Pre-heat your oven to 200 C. Peel your potatoes and boil them. Mash them and add some butter, seasoning, and a bit of grated nutmeg (!) - yes, nutmeg. Flake/cut up you fish fillets and spread into a greased baking dish (I just splashed a bit of oil on the bottom). Add you chopped up onion, peas, celery, and carrot into the baking dish and mix around a bit with some seasoning. Now to make a roux - melt some butter in a saucepan on a low heat, add your finely chopped parsley into this and stir for a bit. Next add some flour (I don't really use exact measurements, so just add enough until the consistency seems right), and stir vigorously until the roux thickens. Boil the milk in a separate saucepan. When it comes to a boil add it to the roux a bit at a time and mix vigorously to get rid of any lumps. When the white sauce reaches the right consistency pour it into the baking dish over the fish. Spread the mashed potato over the top of the fish mixture making sure to cover everything. Place in the over for 30-35 mins. If you want you can grate some cheese over the top. Eat!
Et viola, a lovely fish pie.
