Chicken Paprika (Paprikás Csirke)

Trim the chicken pieces of excess fat and flaps of skin, cut it up, and offer it to your carnivorous garden birds.
Using a deep frying pan or suitable pot, heat a film of oil. Fry the chopped onion, garlic and chicken pieces until the chicken is half-cooked on all sides. No need to brown them.
A very large, deep pot will spare you the agony of those oil spatters and the extra effort of cooking in batches. Use a long-handled wooden spoon to turn the chicken a few time.
While chicken pieces fry, measure the broth or stock into a cup (a metric cup is slightly larger than a US cup). Stir the paprika into the stock.
Add the paprika stock to the chicken, turn heat low, put on lid, and cook for about 30 minutes, until chicken pieces are cooked through and tender.
During this time, scrape the sour cream into a mixing bowl. Add the flour. Whisk the flour into the cream with a wire whisk, until smooth. (Usually sour cream is quite thick).
Remove the chicken pieces to a deep serving dish, and pull the pot with paprika sauce off the heat.
Spoon the sour cream mixture into the paprika sauce in the pot, put back on the heat, and stir with wire whisk until it comes to the boil and thickens. It should be quite thick and smooth, as in the photographs.
Now you have to taste: unless your stock was very salty the sauce will need salt. Add to your taste. You could add pepper, but I skip that.
Pour the sauce over the chicken pieces.
Cover with foil and leave in a warming oven until dinner time (or serve -- whichever suits you). Or cool, cover and refrigerate until the next day.
Best served with rice.
