Add chicken; brown on all sides. Add broth (or water and bouillon cubes) and 2 teaspoons or so paprika. Cover and simmer until chicken is tender (do not boil but simmer; this may take longer). You may want to remove the white meat first. Remove all chicken; keep chicken warm while preparing sauce.
Mix flour and sour cream, add a bit of sauce from chicken and mix together. Put this back into the pot – mix with sauce. Cook 1 minute without boiling. Taste for seasoning – add salt if necessary or more paprika. Return chicken pieces to the pot.
