I keep going to restaurants around my city (São Paulo) where in certain days of the week, some of them serve middle-eastern food.
Curiously, there's always a whitey cream that some of the restaurants call "sour cream" and some of them, call the same cream as "curd".
Also, when looking on the web, I couldn't find much result on which one is right, some pages of middle-eastern cuisine doesn't even list it as one typical food, but they do list baba ghanoush and hummus, that is also served here. Which led me to think that sour cream isn't really from the middle-eastern cuisine, but just misthought to be, as it's similar to baba ghanoush and hummus.
sour cream and
curd different food, or the same? Is it really from middle-eastern cuisine, or just some restaurants that think it is, when it isn't? And if it is, what is the correct name of it?
