Not sure if this is authentic - but it is how my mum made it in my childhood and I still make it her way.
Peel about 12 small shallots and 3-6 large cloves of garlic. Gently fry in olive oil until softened.
Mix a heaped tablespoon of paprika with a tablespoon of cornflour and some salt. Toss 600-800g of stewing steak in it. Add this to the frying pan and cook until the meat is slightly browned. The paprika may come off so make sure it doesn't burn in the bottom of the pan. Add a small splash of water if necessary.
Add 2-3 large carrots, peeled and cut into chunky slices. And three red peppers, peeled, deseeded and cut into chunky pieces. Add a tin of finely chopped tomatoes and about 400ml beef stock, along with another tablespoon of paprika, a few sprigs of thyme, a bayleaf and a small teaspoon of honey. I'd use half and half sweet and hot paprika but if you like it less spicy, use more of the sweet.
Cook slowly in the oven at a low temperature or in the slow cooker for a few hours until the meat is tender and the carrots are soft but not mushy. The sauce should be thick and glossy.
You can add a dollop of sour cream at this stage - either stir it in or put a spoonful on top when serving and then sprinkle very finely chopped parsley and chives on top.
Serve with mashed potato or garlic bread or traditional Hungarian egg noodles (nokedli). And maybe some steamed broccoli or red cabbage cooked with caraway and walnuts as a side dish.
