I think the Portuguese are particularly good preparing and cooking seafood. This Cured Salmon recipe, which is so easy and absolute fantastic, I have learned from a Portuguese Chef I employed and even though he was not Italian, he cooked magnific food in an Italian restaurant.
Fillet the Salmon and take all the bones out with a pair of sharp nosed pliers. Mix 800g Salt, 200g Sugar and the grated rind of four Lemons ( with no pith). Put a thin layer of the salt mixture in a baking tray, large enough to hold the fillet. Place fillet skin side down on the salt mixture and use the rest of the salt to completely cover the fillet. Leave in the fridge for 24 hours, then flip the fillet over and make sure it is again covered with the salt mixture. After another 24 hours, remove from the salt and wash well with cold running water. The timing is absolutely critical to secure a delicious end product, not too dry, not too salty, just right. Dry well with absorbing paper. The cured fish can be consumed immediately or stored in the fridge for about ten days. I cut mine in usable size bits and vacuum seal it, extending the fridge time with some weeks. It is polished off quickly so I have never found out just how many weeks it will keep! Traditiopnally I serve it sliced in paper thin slices – I use my very sharp filleting knife – with capers and a tiny bit of olive oil, fresh rocket salad and home made bread or with some smoked fish roe – do not forget the glass of good red wine (white if you must)
