I don't mean to be rude, but the real "pão de queijo" comes from the State of Minas Gerais (Brazil) and they use only Queijo de Minas, a characteristic cheese from that state, that is very mild, nothing like Parmesan cheese. My god-mother was born and raised in a farm in a small town of Minas Gerais, and I never ate pão de queijo in her home made with any other cheese. The taste is so different you might not recognize it.
These were very good. The recipe intrigued me since it was made in mini-muffin tins. These are definitely at their peak when hot. The batter was mixed in the Vita-Mix which made pouring into the muffin tins easy. Made for PAC Fall 2011.
