Salmon Salsa Verde en Croûte
The traditional Italian salsa verde sauce gives an amazing flavour and a wonderful green layer. Pastry aside, this is a very healthy recipe.
|For the salsa verde:|
|3 tbsp||flat-leaf parsley|
|2 tbsp||fresh basil leaves|
|2 tbsp||fresh mint leaves|
|1||garlic clove, halved|
|2 tbsp||Dijon mustard|
|freshly ground black pepper|
|2 x 350g||salmon fillets, skinned and bones removed|
|375g||packet all-butter puff pastry|
|a little plain flour, to dust|
|1||egg beaten with 1 tbsp milk|
|For the dressing:|
|2||large firm, but ripe tomatoes|
|2||spring onions, finely chopped|
|2 tsp||caster sugar|
|2 tbsp||white wine vinegar|
|4 tbsp||olive oil|
|1/2 tsp||Dijon mustard|
|1 tbsp||freshly chopped parsley|
You will need a food processor.
To make the salsa verde, put the herbs into a processor and whiz until smooth. Add the garlic, anchovies, mustard, egg yolk (egg for 12), and some freshly ground black pepper
(but no salt) and whiz again until smooth.
Arrange one fillet on a chopping board and spread the salsa verde over the top in an even layer. Sit the other fillet on top so it looks like a whole fish.
Cut two-thirds of the pastry from the block (freeze the rest for later) and place on a piece of lightly floured baking parchment. Roll it out so it is long enough and wide enough to enclose the fillets completely. Sit the fillets in the centre and brush the pastry with the beaten egg (reserving some for later). Fold the ends of the pastry over the fillet and bring the sides up to meet at the top. Pinch the edges together with your fingers. Chill for a minimum of 30 minutes.
Preheat the oven to 220˚C (200˚C fan/425˚F/Gas 7) and put a baking sheet in to get hot.Brush the en croûte with beaten egg, then coarsely grate the frozen pastry and scatter on top.
Transfer the en croûte (still on the baking parchment) to the hot baking sheet and bake for 25–30 minutes or until the pastry is golden and cooked at the top and bottom. Allow to rest at room temperature for about 15 minutes.
Meanwhile, make the dressing. Plunge the tomatoes into boiling salted water for 1 minute, then remove with a slotted spoon, plunge into cold water, and drain. Remove the skins, then deseed, cut into dice and tip into a bowl. Add the remaining ingredients, season with salt and freshly ground black pepper, and stir to combine.
Carve the en croûte into thick slices and serve the dressing alongside in a bowl.
