I have bookmark this recipe from Carol 自在生活 and is always under my to do list. The craving for this is even greater when GG say she want to learn how to make this waffler. Without delay I directed her to Carol's link and tell her that I will try out the recipe too. I started doing it last night around 9pm and ended sleeping around 1am. Not too sure why the dough did not double its size despite I have rest it for more then 3 hours. Morning @ 530am I started using my 3in1 waffler maker to 'bake'. It taste nicer when its freshly out from the maker but kind of hard when its cool. I believed it has got to do with the proofing.
