Begin by making your dough. Add the flour to a large bowl and then gently pour in the water, stirring with chopsticks or a wooden spoon simultaneously. Combine until a shaggy dough forms, then begin kneading with your hand for 1 minute until a rough dough forms. You don't want the dough to stick to your hands, so if it is once you've kneaded it, add more flour to dry it out. Wrap it in plastic wrap and set it aside.
Grate your carrot on a chopping board and then top with 1 teaspoon flaky sea salt, 1 teaspoon mixed herbs, 1 teaspoon smoked paprika, and 1 teaspoon ground cumin. Give everything a toss so that the carrot is well coated in the herbs and spices, then set it aside.
Get your dough, knead it for another 10 seconds on a floured surface, then roll it out using a rolling pin into a large very thin sheet of dough.
Brush with olive oil, then evenly spread your leftover turkey all over the sheet of dough, followed by the chopped red onion, and carrot mixture.
Gently roll the dough into a log. Don't worry if the dough tears.
Get a piece of parchment paper and cut out little breathing holes, place it down onto your steaming basket and then top with the dumpling roll. Get both ends of the roll and pinch them together forming a circular wreath. Steam for 12 minutes.
Once your dumpling wreath is cooked, remove it gently from the steamer and place onto a serving plate. Top with yoghurt, your harissa oil, chopped chives, chopped coriander, and sliced chilli.
