serves 4
4 haddock fillets
8 prosciutto slices
1/4 cup finely chopped onion
1 cup leeks (white part only) finely chopped
1 garlic clove, minced
3 to 4 tablespoons heavy cream
frozen puff pastry, thawed in the fridge
1 egg, beaten slightly
Preheat oven to 425f.
Pat dry haddock fillets. In a frying pan over medium heat add a splash of olive oil. Add onions and leeks and cook until soft. Stir in garlic until fragrant. Add cream and stir. Remove from heat and allow to cool. To speed up process, place in fridge. The cream will help bind the leeks and onion to the consistency of a loose paste.
Lay pastry on a work surface and cut in half (if using sheets). The pastry I purchased had 2 sheets per box. Have prosciutto slices ready to work with. On another work surface, tuck fish fillet ends under to make a neat parcel. Add about a tablespoonful of the leek paste and smear over top of fish. Place fish fillet at one end of the prosciutto and roll up. Take another prosciutto slice and repeat. Move the prosciutto wrapped fish and place it at the top of the puff pastry. Use a pastry brush to coat the sides of pastry with egg wash. Roll up, pinching sides. You may not need the whole piece so cut off any excess pastry. Use a fork to crimp the edges. Repeat process with remaining fish fillets. Make 2 or 3 small slashes in the top of the pastry and place all fish parcels on a parchment-lined baking tray. Place in the fridge for at least 20 minutes or leave until your guests arrive.
