Golden Potatoes With Caper Brown Butter Crumbs Recipes

Steps:

• Heat the oven to 375 degrees Fahrenheit/180 degrees Celsius.
• Add 2 tablespoons/30 grams of butter and all the oil to a medium (10-inch/26-centimeter) ovenproof sauté pan over medium-high heat. Once melted, add the onions and 1/2 teaspoon salt, turn the heat down to medium-low and cook, stirring occasionally, until onions are softened and have taken on a light coloring, about 15 minutes. Add the garlic and thyme leaves, and cook for another 3 minutes, stirring occasionally, until fragrant. Stir in the miso and wine, and cook until liquid is reduced by half, about 4 more minutes. Remove from the heat.
• In a large bowl, very gently toss together celery root (celeriac), potatoes and flour with 1 1/2 teaspoons salt and a generous grind of pepper. Stir in the onion mixture to coat, then transfer everything back into the skillet, piling the vegetables haphazardly, so that the batons are pointing in different directions. Pour in the stock. Lightly grease a piece of foil with a little oil, then tightly cover the pan (oiled side down) and bake for 1 hour, or until the vegetables have cooked through.
• Remove the foil, and turn the oven temperature up to 450 degrees Fahrenheit/210 degrees Celsius. Sprinkle over the Gruyère and return the dish to the oven for 30 minutes, or until nicely browned on top, rotating the dish halfway. Leave to settle for at least 20 minutes while you make the brown butter (beurre noisette).
• Add the remaining butter and the thyme sprigs to a small saucepan, and place it over medium heat. Once melted, cook for 3 to 5 minutes, stirring occasionally, or until it starts to smell nutty (add more or less time if necessary). Add the capers (carefully, as they might spit) and cook for 4 more minutes, or until they darken and burst. Off the heat, stir 1 tablespoon lemon juice from 1 lemon, chives and another good grind of pepper.
• Pour the caper brown butter all over the top of the gratin and serve warm, with the remaining lemon sliced into wedges to squeeze alongside.

Steps:

• Up to 2 days ahead, boil the potatoes for 2 mins, then drain and leave to cool.
• Thirty mins before serving, melt the duck fat in a large frying pan and add the potatoes. Start them on a high heat to get some colour, then turn the heat down to sizzle the potatoes slowly for 20 mins, shaking the pan occasionally, until completely golden and crisp.
• Just before serving, toss through the parsley and garlic, season with salt and serve.

Steps:

• To make the purée, melt a small knob of butter in a saucepan, add the celeriac and cook over a medium-high heat until starting to brown a little, about 5 mins. Pour over the milk and cream, and season well - the celeriac should be just covered, so add more milk if needed. Bring to a simmer, cover and cook for 15 mins or until tender. Drain, reserving the cooking liquid, and transfer to a food processor. Blend until smooth, then sieve into a clean saucepan, pushing the celeriac through with the back of a spoon or spatula. Add a little of the cooking liquid to loosen the purée if needed, and taste for seasoning.
• To make the crumbs, heat a small knob of butter in a frying pan, add the breadcrumbs and cook, stirring, until golden brown. Throw in the capers and cook for 30 secs more. Tip into a bowl and leave to cool a little, then stir through the parsley.
• Heat oven to 140C/120C fan/gas 2. Gently melt the butter in a small ovenproof saucepan or frying pan, big enough for the fish fillets to fit snugly. Once melted, add the shallot, bay leaf and peppercorns. Keep heating until the butter turns a light brown colour and smells nutty. Leave to cool a little. Gently lower the fish fillets into the warm butter, basting any exposed fish, and transfer to the oven. Cook for 3-4 mins, depending on the thickness of the fish, then turn the fillets over and cook for a further 3-4 mins or until just opaque and feeling firm.
• While the fish cooks, reheat the purée and steam the greens. To serve, spoon the purée into the centre of each plate; use the back of the spoon to spread out slightly into a circle. Top with the greens, then carefully place the halibut on top. Drizzle with a little of the poaching butter and scatter with the crumbs.
