This intense duck dish from Sam Yorke uses all parts of the duck; the bones and trim go into the sauce, while the breasts are carefully cooked sous vide. The sides – pickled redcurrants and radicchio, and puréed beetroot – make more than you'll need for this recipe, but are delicious with other roast meats.
Brine the duck in a 5% salt solution for 1 hour in the fridge
Remove, dry well, then break down the duck
Vacuum seal the duck breasts and cook sous-vide at 58°C for 1 hour. Once cooked, chill immediately in ice water to stop cooking and firm up
For the duck sauce, heat 5 tablespoons of vegetable oil in a pan. Fry the duck bones and trim until caramelised
Drain the contents of the pan through a colander, discarding the oil. Put the duck trim back into the saucepan
Pour in half the chicken stock and reduce on a high heat until almost dry
Once dry, add the remaining chicken stock and reduce by half
Strain the liquid through a fine chinois into a clean container. Place in the fridge to chill overnight
The following day, skim off any solidified fat, then reduce until thick enough to coat the back of a spoon
For the pickled redcurrants, bring the vinegar, water, sugar, and salt to a boil
Pour the brine over the redcurrants and allow to pickle for at least 1 hour
For the radicchio, heat the water, vinegar, sugar, and salt until boiling
Pour over the radicchio wedges in a container and leave to pickle for at least 1 hour. This will finish the cooking process
Add the walnuts, green peppercorns and 20g pickled red currants to the duck sauce
Boil the beetroots until tender, then strain the water, reserving the liquid
Blend at full power until smooth, adjusting the consistency with the strained water
Pass through a fine chinois
Season with salt and a splash of sherry vinegar
Place a dot of beetroot purée onto each plate
Fry the duck breast on a medium heat until golden brown and the skin is rendered and crispy. Rest for six minutes
Sauté the girolles in butter until cooked
Reheat the pickled radicchio on the barbecue
Add a few leaves of pickled radicchio and the girolles
Slice the duck breast and place on the plate, skin side up. Spoon over duck sauce
