For pommes Sarladaise, place potatoes in a large saucepan of cold salted water, bring to the boil over medium-high heat, cook until just tender (10-15 minutes). Drain, cool, cut into 5mm-thick rounds. Heat duck fat in a separate large deep-sided frying pan over high heat until shimmering, cook potatoes in batches, turning often until golden (3-5 minutes), drain on absorbent paper, season, keep warm.

Preheat oven to 200C. For dill sauce, cook Pernod, shallots and wine in a small saucepan over medium-high heat until reduced to 60ml (5-7 minutes). Add cream, reduce by half (5-7 minutes), add dill, process in a blender until smooth, season, keep warm.

For pistou-crusted barramundi, process herbs, walnuts and garlic in a food processor to a coarse paste. With motor running, add olive oil in a thin steady stream until emulsified. Season to taste, thickly spread on skin-side of barramundi (you may have a little remaining), then roast on a baking-paper-lined oven tray until just cooked through (6-8 minutes).

Meanwhile, heat wine and 20gm butter in a saucepan over medium heat, add vongole, stir until open (3-5 minutes), keep warm.

Heat remaining butter in a frying pan over medium-high heat until foaming, add garlic, stir for 1 minute, then add silverbeet, stir until just wilted (1-2 minutes). Season, divide among plates, top with potato, vongole and barramundi, spoon over dill sauce and serve.
