What berachah / berachot do you say on cholent, containing barley, beans, potatoes and meat?
Depends on what’s in the bowl and in what amount.
Two bowls from the same chulent can have different brachot.
Visible pieces of barley, pieces of potatoes, pieces of meat- three berachot?
One bracha if its a chulent.
If just about every time you take a spoonful from the bowl it has barley then the bracha would be mezonot. Otherwise, whichever has more.
