I don't know in Spanish, but in Hungarian it is called a soup... Also, I remember one that I hate it and it looked even more similar to your thing, but that is more a Serbian cusine... (no offense 😂)... When my mom would prepare it, it would be like a soup, she would put in 4-5 plates, and store it in a refrigerator (not freezer), or in a cold room if it was winter...
When it got cold, it would be like a jelly, with pieces of meat (on the bone), that you would eat more with fingers than cutlery... lol..
