Hi i have a few questions about this dish, say i make 1lb of bq pork on tuesday then put it in the fridge and make the buns the following day can you freeze the buns until you need and when they they are defrosted resteam them. Is it safe to do this with pork as effectively you would have cooked it 3 times , 1st to make the bbq pork , then to steam initally , then steamed again after defrosted , should i instead freeze the buns straight after they are made.
