I think you may talking about 'pau' or 'bau' which is a steamed bun that can have a sweet or savoury filling. The sweet variety can be filled with a lotus bean paste or sometimes red bean paste (I think it's also called aduki beans). A common savoury filling is made with chinese roast pork, but there are other fillings too. Looks like this: http://www.smokywok.com/2011/02/stea...ns-recipe.html ? It's common to get both sweet and savoury versions as part of a dim sum selection, at least over here and in the Far East.
