This zander fish dish from Kuba Winkowski uses smoked butter to give the buttermilk broth a smoky flavour, and layers the flavour of dill in a dill oil, dill pesto and delicate dill kopytka (a sort of Polish gnocchi).
Score the skin of the zander fish, and set aside in the fridge until needed
Bring the fish stock to the boil and add the dill stalks. Remove from the heat, cover with cling film, and set aside to cool
Once cool, strain out the dill stalks and then return 250g of the stock to the heat
Melt the smoked butter for the broth into the 250g of infused stock, but don’t let the stock boil. Add the remaining broth ingredients and then blend everything together until smooth
Strain the solids through a muslin cloth set in a fine sieve over a bowl
Cool the strained oil over an ice bath to help keep it bright green, and then discard the leftover pulp
Heat the smoked butter for the mushrooms in a pan and, once melted, add the chanterelles and a pinch of salt. Cover with a lid and cook for 30 seconds, then add the lemon juice. The mushrooms should be bright yellow and not have released any liquid. Set aside
For the dill pesto, place the dill, salt, pepper and garlic into a jug blender. Drizzle in the oil with the machine running, and then blend for about one minute or until smooth but not overheated
Blanch the broad beans in salted, rapidly boiling water for 1–2 minutes, then refresh in ice cold water
Skin the blanched broad beans and set aside
Cooked the peeled potatoes in salted water until tender, then drain and pass through a potato ricer
Roll out the dough out into a 1 cm thick log, and then gently flatten it slightly. Cut the log into 1cm long pieces
Blanch the gnocchi in salted boiling water for about 3 minutes. Drain and then refresh in ice water
Once ready to serve, gently warm up the buttermilk broth
Heat up a dash of olive oil in a non-stick pan, and season the portions of fish
Cook the fish skin-side down until golden brown and crispy, then turn over and cook on the other side. Squeeze over some lemon juice and baste the fish
Remove from the pan just before it is fully cooked, as it will continue to cook while resting
Warm up the chanterelles, dill kopytka and broad beans with an extra knob of smoked butter, then remove from the heat and mix with the dill pesto. Taste and adjust seasoning if necessary
Place about 10ml dill oil in the base of four serving jugs (one jug per person)
Transfer the mushroom mixture to a bowl and top with the fish. Garnish with more dill, and pour over the broth and dill oil mixture to serve
