Preheat the oven to 200°C and prepare the stock. Chop the leek into thin rings. Core and quarter the fennel, then cut it into 2cm chunks. Chop the onion and crush or mince the garlic.
Melt a generous knob of butter in a deep frying pan over medium-high heat and fry the garlic and onion for 1 - 2 minutes. Add the leek and fennel and continue cooking for 4 - 5 more minutes, then stir in the flour and fry for 1 more minute. Deglaze with the stock and white wine vinegar, then mix well and allow to simmer gently for 8 - 10 minutes. Season to taste with salt and pepper.
In the meantime, dice the tomato and finely chop the parsley. Boil plenty of salted water in a pot or saucepan for the potatoes. Peel or thoroughly wash the potatoes, then cut into rough pieces. Pat the fish and the shrimp dry with kitchen paper.
Reduce the heat under the vegetables and then stir in the cream, shrimp, tomato and half of the parsley. Season the fish with salt and pepper, then transfer to an oven dish and pour over the creamy sauce. Scatter over the grated cheese, then bake in the oven for 15 - 20 minutes. Meanwhile, boil the potatoes for 12 - 15 minutes, covered, then drain and set aside.
Mash the potatoes with the mustard, a knob of butter and a splash of milk. Season to taste with salt and pepper and mix well to combine.
Serve the fish gratin with the mashed potatoes. Garnish with the rest of the parsley.
