First of all, rinse your pieces of lamb under the tap and add to your large saucepan.
Place on the hob on a high heat and add around 2.5 litres of water and start to bring to the boil.
Add your tomato / pepper paste, paprika, salt & pepper and stir.
When the water is boiling, cover and turn a low heat.
Leave to simmer for 90 minutes to 2 hours, until the meat falls easily from the bone.
Now remove from the heat and remove the lamb from the stock with a slotted spoon. Leave the meat to cool.
Your whole garlic cloves will now be really soft and sweet. Squash these into your stock.
Meanwhile, cook your rice by adding around 20 grams of butter to your small saucepan and heating over a medium heat.
Add your rice and stir around for a couple of minutes before adding hot water. Add double the amount of water to rice.
Bring the rice to the boil and then cover and cook over a low heat for 10 minutes.
After 10 minutes, remove the rice from the heat and leave to stand, covered, for 5 minutes before forking through it.
Once your lamb has cooled, pull the meat away from the bone and tear into small chunks. Discard the bones and any big pieces of fat.
When you're ready to eat your soup, place your stock back onto the heat and add your hot chilli flakes (red pepper flakes) and grated garlic.
Bring to a rapid boil for about 10 minutes and add your lamb meat before removing from the heat.
Portion your rice out between 6 bowls and ladle your bubbling hot soup over the top.
Sprinkle with sumac, mint and more chilli if you like and squeeze fresh lemon juice over the top.
