2 small carrots, peeled, coarsely chopped
2 tbsp olive oil
1 onion, finely chopped
2 tbsp currants
1 tbsp red wine vinegar
600gm coarsely minced lamb
200gm coarsely minced chicken
1 cup (loosely packed) flat-leaf parsley, finely chopped
40gm (½ cup) sourdough breadcrumbs
4 garlic cloves, grated
2 tsp eachground cumin and ground coriander
1 tsp dried chilli flakes
Finely grated rind of 1 lemon
1 egg, lightly beaten, plus 1 extra, lightly beaten for eggwash
2 sheets butter puff pastry (375gm each; see note)
2 tbspnigella seeds Yoghurt sauce
250gm Greek-style yoghurt
2 garlic cloves, finely grated
½ cup(firmly packed) mint, coarsely chopped, plus extra to serve

Preheat oven to 180C. Combine carrot and half the oil in a bowl, season to taste, spread over a baking tray lined with baking paper, cover loosely with foil and roast until tender (30-35 minutes). Remove foil and roast until very tender and golden brown (8-10 minutes). Cool, then process in a small food processor and set aside.
Heat remaining oil in a frying pan over medium heat, sauté onion until softened and translucent (6-7 minutes). Set aside to cool. Combine currants, vinegar and 1 tbsp water in a small bowl and set aside to soak until plump (15 minutes), then drain.
Combine lamb, chicken, parsley, breadcrumbs, garlic, spices, lemon rind, egg, carrot and onion in a bowl, season to taste and mix well.
Roll each pastry sheet on a lightly floured surface to 3mm thick. Form a 2.5cm-thick cylinder of lamb mixture on each sheet of pastry 1.5cm from the edge, brush pastry with eggwash, then roll to enclose, press to seal and trim at seam. Transfer to a tray, refrigerate to chill and firm (30 minutes), then trim ends and cut each roll into 5cm lengths. Place on baking trays lined with baking paper, score tops with a sharp knife, brush with eggwash, scatter with nigella seeds and bake until golden and cooked through (25-30 minutes).
Meanwhile for yoghurt sauce, combine ingredients in a bowl, season to taste and stir to combine. Serve scattered with extra mint and rind with hot sausage rolls.
Note: Makes 24 sausage rolls. We prefer to use Carême puff pastry, which comes in 375gm sheets. If it's unavailable, use another good-quality butter puff pastry.
