Step by step

Add the stock to the meat and veg mixture until it just covers everything, bring to the boil, and continue to add stock as it evaporates. Add spices and cook for a long period until the meat is tender.

Tips
If you want to taste proper Hungarian goulash you must not in any way exceed the cooking times: in fact, the real recipe does not result in what we would call a stew, but is more similar in appearance to a soup.
Trivia
The meaning of the term in Hungarian ‘gulyas-leves’ (this is its proper name) is simply ‘herdsman soup’; ‘goulash’ derives from the German transliteration of the original name of this recipe.
