Poaching the trout in large pieces ensures it retains its beautifully moist texture.

Bring wine, onion, bay leaf, peppercorns and 2 litres water to the boil in a wide saucepan over medium-high heat. Season to taste with sea salt, add fish, remove from heat and stand until cooked to your liking (10-12 minutes for medium-rare).

Meanwhile, blanch baby vegetables until tender (2-4 minutes), then refresh and drain well. Heat butter in a wide saucepan over high heat, add baby vegetables, cook until warmed through (2-4 minutes), season to taste and keep warm.

For lime beurre blanc, simmer wine, lime juice and shallots in a saucepan over medium heat until reduced to 80ml (5-10 minutes). Add cream, bring to the simmer, season to taste, then reduce heat to very low and add butter a little at a time, whisking continuously, until incorporated. To serve, spoon vegetables and reserved fennel fronds onto plates, top with fish, scatter with chervil and spoon over lime beurre blanc. Serve hot with extra sauce and lime wedges to the side.
