“And now comes the black soup.”
In Hungarian, this saying refers to a forthcoming negative incident. It has a supposed origin in the times of the Ottoman-Turkish Occupation of Hungary.
The anecdote says that a Turkish lord invited a Hungarian lord to a dinner. The Turks regularly drank coffee (“black soup” as they said) after the meal. When the guest finished his meal and wanted to leave, the Turk said: “Do not go, the black soup is yet to come”. That was a password for his servants to rush into the room and capture his guest.
