Cooking Fish

Poaching Fish
  This is a method sometimes refered to as boiling, but that is incorrect, for the water should only simmer very gently, or 'shimmer'.  
  Poaching can be done in a saucepan, frying pan ( skillet ) or fish kettle, on the hob or in a shallow covered container in a moderate oven 9 1800C / 3500 / Gas mark 4 ).
   The fish to be poached can be filleted, in steaks or cutlets or be small whole fish, including haddock and kippers, or larger pieces and whole fish that are traditionally poached, such as salmon, sea trout and pike.  The larger pieces and whole fish are usually cooked on the hob.  The poaching liquid can be fish stock, milk, wine or water, etc, or a Court Bouillon, which is a traditional liquid used for poaching whole fish.

Heat the chosen liquid in a suitable sized pan, gently lower the fish - using strips of double foil to help maneuver it if a very large fish - and heat gently until it just returns to simmering.  The liquid must cover the fish completely if it is a large whole fish.  Cover the pan and simmer gently until just tender - allow 10-15 minutes per 450g / 1lb.  The thicker pieces will need the longer cooking time; a piece weighing say 675g / 11/2lb should only need 20-25 minutes.  A knife can be gently inserted into the fish to lift up a flake and ascertain if it is cooked.  Do not overcook or the fish becomes dry and tasteless.
  When ready, drain the fish thoroughly and place on a warmed serving dish.  Serve with a sauce made including some of the cooking liquid.
  If cooking fillets of fish, they may be laid flat, folded or rolled up ( known as paupiettes ) and they need only half covered with the cooking liquid.


Grilling or Broiling Fish
   This is one of the more popular ways of cooking fish, especially steaks and cutlets and small whole fish.  Trout, herrings, small plaice or flounder and sole, kippers etc, all benefit from this method, but watch the lingering smell after grilling kippers!  Filleted fish may also be grilled; it is probably best to line the grill tray or rack with foil and brush lightly with oil or melted butter before grilling.  This will help prevent the fish sticking and mean at the end, the fishy smells can be folded up and discarded.
  Wash and dry the fish first and, if whole, remove the scales and cut off the fins.  If it is a particularly plump whole fish ( e.g. herring mackerel, sea bass ), it is a good idea to make 2 or 3 diagonal cuts in the body flesh on each side to allow the heat to penetrate more quickly during cooking.
  White fish such as plaice or flounder, sole haddock cod, halibut, etc. should be brushed with melted butter or oil to prevent drying out during cooking and placed in the grill pan; oily fish such as herrings, salmon and mackerel do not need extra fat.  If on a diet, use lemon juice in place of oil and add extra during cooking.  A little salt and pepper can also be added.
  Thin fillets or steaks can be cooked on one side only, but it is more usual to turn the fish halfway through cooking.  Use a fish slice and/or palette knife or spatula and do so very carefully as fish are very fragile when cooked, especially flat fish.
  Turn the grill or broiler on to moderate and allow about 5 minutes for thin fillets or 10-15 minutes for whole fish and steaks, turning these over halfway.  Take care not to overbrown - burnt fish flesh is not very appertising.



Baking Fish
  This method is equally good for steaks, fillets and small whole fish as well as large fish, such as whole sea trout and salmon.

1  Was and dry the fish and prepare as required.  The fish may be stuffed if liked, or as a whole fish, with the bones removed, or wrapped up in fillets.

2  Put into an ovenproof dish with salt and pepper, a bay leaf or bouquet garni and about 60ml / 4 tbsp of liquid ( water, wine milk etc. ).  Cover with a lid or foil.

3  Cook in a moderate pre-heated oven at 1800C / 3500F / Gas mark 4, unless otherwise directed in the recipe - large whole fish require a lower temperature - allowing about 10-20 minutes for fillets, 20-30 minutes for steaks, 25-40 minutes for small whole fish or until tender.  Solid pieces of fish will need a little longer, but test after 30-40 minutes.  The flakes should lift away easily when cooked if you insert a small palette knife or spatula.

4  Alternatively, wrap the prepared fish in buttered foil after adding seasonings, a squeeze of lemon juice and possibly a bay leaf and stand in a roasting tin or dish.  Bake at the same temperature as above, allowing about 25 minutes for steaks, or 10-15 minutes per 450g / 1lb for large pieces, or as directed in the particular recipe.

5  Serve the fish with a sauce made using the juice that will have accumulated in the casserole or foil.

Shallow Frying
  This method is suitable for all types of filleted fish, steaks and cutlets and small whole fish that serve just one portion, such as sole, plaice, dabs, flounders, bream, cod, haddock, mackerel, herrings, trout, perch, pike, etc.  Oil or lard is usually best, but to cook it ' à la meunière ' ( a special way of shallow frying ) the fat must be butter.

1  Prepare, wash and dry the fish, and coat either in seasoned flour ( add salt and pepper to about 60g / 2oz of flour and roll the damp fish in it so it sticks ) or in egg and breadcrumbs ( beat an egg with 10ml / 2tsp water and seasonings and dip the fish first into this and then roll in bought golden breadcrumbs, or freshly made white breadcrumbs, which may be made from stale bread, pressing them well in so they stick ).

2  Put about 1cm / 1/2 inch of oil or dripping into a frying pan and heat until fairly hot - not smoking hot, which will burn the fish without cooking it properly.

3  Put the fish in carefully so that the side to be served facing upwards cooks first.  Cook gently until the first side is browned - about 5 minutes, turn over very carefully, and cook the other side until ready.

4  Remove from the pan with a fish slice or slotted spatula and drain on crumpled kitchen paper towel.  Keep warm whilst frying the remainder.

Deep Frying
  The traditional British fish and chips are cooked by this method in a large pan of oil or fat.  This method is easy to carry out at home provided you have a suitable pan for cooking.  It should be a fairly large deep pan with a wire frying basket that fits inside or alternatively, you can use one of the special electric deep-fryers, which are most efficient and clean to use..
  Cooking oil, lard or clarified dripping can all be used and the pan should be filled to half full - but no more for safety's sake.  The fat must be free of moisture or it will "spit" during heating.
  The oil should be heated to 177-1880C / 350-3700F and the simplest way to test this is to fry a cube of bread which should take 50-60 seconds to brown evenly.  Fat that is too hot will give an overcrispy brown coating with raw or partly cooked interior or, if too cool, the fish or whatever is to be fried will be soggy.
  Coat the fish in egg and breadcrumbs ( or batter ) while the fat is heating.  Do not cook battered fish in the basket, it will pull off during cooking; add carefully and lift out with a slotted spoon.  It is most important to cook only a small amount at a time ( e.g. two fish fillets ) or the temperature of the oil will be lowered to quickly and not cook sufficiently.  Electric fryers tell you when the oil temperature drops by a light coming on or off, provided you have set it at the correct temperature for what you are frying.
  As soon as the fish ( or whatever ) is cooked, it should be removed from the fat with a slotted spoon or by lifting out the wire basket, allow the excess oil to drain back into the pan, then drain on crumpled paper towel.  Serve as quickly as possible after cooking for the coating will become soggy if kept hot for long.
  The oil an be cooled and strained into a clean bowl ready for future use.  Oil will not keep indefinitely, as it darkens with cooking and also becomes tainted with the food flavours, but straining after use will prolong it's life.
