25 min. | 35 min. | 60 min. |
1 | Poach 800 g Fish in 1 litre fish fumet (or, at a push, just use salted water with 1 Bouquet garni) at a gentle simmer until just cooked. To ensure the fish is perfectly cooked, stick an electronic thermometer into the fish and cook until the temperature reaches 140°F (60°C). | |
2 | Take the fish out of the cooking liquid, remove the skin and any bones, then flake (break up) the flesh. Set aside. | |
3 | Prepare and slice 2 onions finely (a mandolin is the ideal tool for this). | |
4 | Pour 3 tablespoons olive oil into a saucepan on medium heat. When hot, add the sliced onions. | |
5 | Salt and pepper, then cook for about 5 minutes - the onions don't need to brown. Set aside. Preheat the oven to 360°F (180°C). | |
6 | Peel 800 g cooked potatoeses (I'm using rattes here). | |
7 | Cut the potatoes into small pieces, then mash coarsly with a fork. | |
8 | Add the fish, onions, thyme, salt and pepper, and mix well. | |
9 | Fill individual ramekins or a large gratin dish. Top with grated cheese. | |
10 | Bake for 20 minutes, just until the cheese on the top has melted and is nicely browned. Finish browning under the grill if necessary. |
