Birkapörkölt is a wonderful mutton stew from the Hungarian Great Plain. It is simplicity personified, slow-cooked mutton with loads of onions and paprika that's finished with a bit of offal.
Heat a 20cm or 8" saucepan over a high heat and when it is hot, add the lard, when it melts throw in the mutton and cook it until it becomes nicely coloured stirring regularly. Then reduce the heat to medium and cook for 25 minutes, stirring every 10 minutes or so.
Whilst the mutton is cooking, peel the onions and cut a third of them (around 150g) into rounds approximately 5-6mm (¼") thick and cut the rest into a 5mm-6mm (¼") dice.
Peel and roughly slice the garlic cloves.
When the mutton has had 25 minutes, reduce the heat to low, sprinkle over the diced onion, sliced garlic and dried chill peppers and give everything a stir.
Pour over enough water to just cover the mutton, then sprinkle over 3 tablespoons of the paprika (we will add the final tablespoon later). Do not stir in the paprika; just sprinkle it over the top as evenly as you can.Cook gently for another 3 hours, topping up with water if needed; do not stir the stew during this phase.
Cut the lamb liver or kidney into a 2cm (¾") dice.
After the lamb has been cooking for 3 hours, add the lamb offal and onion rings and give everything a stir, and add a little more water if required.Sprinkle over the remaining tablespoon of paprika and cook for a final 25-30 minutes. After 30 minutes, give everything a stir and serve.
