About this dish
A true Dieppoise sauce celebrates the Normandy coast with cider, cream and butter, traditionally built around mussels or sole — here that same rich foundation is ladled over crisp, golden potato galettes instead, with leeks and briny capers standing in for the seafood. The result carries all of the coastal character of the original with none of the fish, a comforting plate that is entirely vegetarian.

Method
Coarsely grate the potatoes using a box grater or food processor. Working in small handfuls, wring the grated potato tightly in a clean tea towel over the sink, removing as much liquid as possible. Transfer to a large bowl. Add the beaten eggs, flour, ½ tsp salt, and white pepper, and stir to combine evenly.
Cover the potato mixture and rest at room temperature for 10 minutes while you prepare the sauce ingredients.
Melt 20g of the butter in a wide sauté pan over medium heat until foaming subsides. Add the shallots and leeks with a pinch of salt and cook, stirring occasionally, for 8-10 minutes until completely soft and golden at the edges.
Add the garlic and thyme to the leek mixture and cook for 1-2 minutes, stirring constantly, until fragrant.
Pour the cider into the pan, raise the heat to medium-high, and simmer for 4-5 minutes until reduced by half and the sharp alcohol smell has mellowed.
Reduce the heat to low, stir in the crème fraîche and capers, and cook for 3-4 minutes, stirring gently, until the sauce thickens to a consistency that coats the back of a spoon. Remove from heat, stir in the parsley, and season to taste. Keep warm on the lowest heat setting.
Heat 1 tbsp oil and 20g butter together in a large non-stick or cast-iron skillet over medium-high heat until the butter foam begins to subside and the pan is shimmering. Working in batches, spoon four mounds of the potato mixture (roughly 120g each) into the pan, pressing each down firmly with a spatula to form a disc about 1cm thick. Cook without moving for 4-5 minutes until the underside is deep golden-brown and releases cleanly from the pan.
Flip each galette and cook for a further 4 minutes until the second side is equally golden and the potato is cooked through. Transfer to a wire rack in a low oven (100°C) to keep warm.
Repeat with the remaining oil, butter and potato mixture to cook the second batch of galettes the same way.
Plate two galettes per person, spoon the Dieppoise sauce generously over and around them, and finish with a grind of white pepper.
