Begin by combining your flour, salt, and water in a bowl. Mix with chopsticks, a wooden spoon, or your hands until a rough dough forms. Then, pour it out onto a clean surface and knead for a couple of minutes. The dough should not stick to your hands, if it does, add more flour. Wrap it in cling film and set aside.
In another bowl, combine beef mince, chopped wilted spinach, chopped red onion, minced garlic, salt, pepper, and an egg. Mix thoroughly and add a little bit of flour if the mixture is looking a bit wet.
Get your dough and knead it once gain for 30 seconds on a clean surface. You should notice that the dough has softened. Form it into a doughnut and then widen the hole. Slice into a log and then cut the log into 16 equal-sized pieces.
Get yourself a piece of dough and roll it out into a circular wrapper around 3 to 4 inches in diameter (dust with flour to avoid sticking). Place a spoonful of the filling into the centre of the wrapper and then fold and pinch in an anti-clockwise direction. Seal, then flatten slightly. Repeat for all dumplings.
Place a non-stick frying pan on medium heat and drizzle with oil. Add in your dumplings (don't stack them - you may need to put two frying pans on the go) then pour 100ml of water into the pan. Cover with a lid and leave to steam for 6 minutes. Uncover the pan, drizzle with a bit more oil, and leave to fry for 2 more minutes or until the bottoms of the dumplings are golden.
While your dumplings are cooking, combine the ricotta, lemon zest and juice, pepper, salt, parmesan, mayonnaise, and sesame seeds in a bowl. Whisk until well combined. Additionally, combine 1 tablespoon harissa paste and 2 tablespoon vegetable oil in a small bowl. Place in the microwave for 30 seconds. When your dumplings are cooked, place them onto your serving plate and top each of them with whipped ricotta, harissa oil, and chopped chives.
