Most Bulgarians eat "кисело мляко" (sour milk) every day, some mix it with water + some salt to make "айрян", which is a drink :-) The so called "yogurt" has nothing to do with "кисело мялко". I am not saying that yogurt is bad, it's just some powder milk + emulgators + sweeteners, produced by companies like Danone, Nestle etc. We have hundreds of brands, but only a few produce the "real deal"...free market, you know :-)

Turks, coming from the East, would be known to use and consume yogurt regularly, as do so many asianic cultures, in their food for taste and to balance the lit-ass spices (technical term for hot-ass and stanky-ass).
