- Heat your oven to 180°C.
- Lay the lamb shoulder on a large oven tray; add the onions, salt, pepper, 2 tbsp of sunflower oil, the honey mustard and rub well over the meat. Add 100ml of water and cook in the oven for two and a half hours turning the joint every 30 minutes.
- Cool the meat and and shred it and put to one side.
- In a cooking pot large enough to contain all the ingredients, add 2 – 4 tbsp of sunflower oil (enough to coat the potatoes) and the sliced potatoes. Shallow fry them on both sides until golden and starting to crisp up.
- Pour boiling water over the spinach to wilt it. Drain and put aside.
- Rinse the rice until the water runs clear.
- In another large non-stick pot, add 150ml sunflower oil, the onion and garlic and fry at medium heat until they are soft and starting to brown.
- Add the rice and stir. Add the parsley, lamb, spinach, spices, harissa and mix.
- Add 900ml of water (I use cups to measure the volume of water using a ratio of 1.5 cups of water for 1 cup of rice.)
- Cook uncovered over a high heat, turning down to medium when the water starts to boil, and stirring regularly until the water evaporates. Taste in order to correct the seasoning — it will be hard to do this one the rice has set.
- Spoon this over the fried potatoes and leave it to cook over a medium heat for 6-8
- To serve, using oven gloves to hold the plate tightly over the pan, invert the pan over a large serving dish.
- Serve immediately, or cover with foil until ready to serve. You can warm it in the oven for 10-20 minutes at medium temperature if you want to serve it hot.
