This is such a lovely recipe and much lighter and less expensive than beef Wellington.
Gloria used to cook for my mother and father after my mother became ill and I remember her making this, but I’ve never seen the recipe in any book.
It’s well worth trying and you can also make a nice cream fish sauce to go with it,  but it’s not necessary.

4 rashers bacon, finely chopped
1 medium onion finely chopped
1lb white fish  fillets, chopped
1/2 cup fresh white breadcrumbs
1/2 cup cream
2 eggs, separated
1 tbsp dried dill weed
1 packet frozen puff pastry, thawed

Preheat the oven to 350 F
Combine the bacon and onion in a small frying pan and cook for about 3 minutes or until soft.
Put the fish, breadcrumbs, cream, egg whites and dill in a food processor and process until combined.
Empty into a bowl and stir in the bacon mixture and season with salt and pepper to taste. Tip into  a 8″ by 5″ greased loaf tin and bake uncovered for about 45 minutes.
Cool to room temperature.
Roll the pastry to about 10″ by 14″ rectangle and brush the edges with the beaten egg yolks.
Place the fish loaf in the center of the pastry rectangle, roll up, seal and trim any excess pastry around the edges.
Place onto a greased baking tray and brush all over with beaten egg yolk.
Bake until golden, about 30 mins or so, depending on your oven. Check occasionally.
