I’ve been thinking about fish pies.
Here’s a recipe from Ely Wine Bar – I think it’s a fine restaurant:

Here’s one from Gordon Ramsey – he knows how to cook:

And finally here’s one from Rick Stein – he knows more about fish than almost anyone:

What do they all have in common? First they poach the fish for about 10 minutes, and then put the fish and some sauce, covered by mashed potato into an oven for up to 40 minutes.
I make lots of fish pies, and I find it increasingly strange that anyone would want to cook fish for nearly an hour. You can poach a whole salmon in that time! When using fillets or similar they’re generally completely cooked during the poaching process.
One thing that the poaching does is to remove some of the water from the fish – that’s why most of the sauces are made from the poaching liquid – to get that flavour back into the sauce.
So now I make the béchamel so thick that a spoon will stand up in it – you can almost slice it. I mix the sauce with the uncooked fish, Then I top it, first with hard-boiled eggs (I love them in my fish pies, though I know they’re not to everyone’s taste) and then the potato, and put the whole lot into the oven for 40 minutes.
The liquid comes out of the fish during the cooking and makes my sauce the runnier consistency I want – and my fish has been cooked slowly, in the sauce, for about 40 minutes.
