Normally it is a commercial product...So if you have a local bakery/bread manufacturer nearby. Just try them. IE ask to see the manager and ask him/her. Same for a local supermarket that makes breads etc. I would ask for 500 gms which would be 1/2 a packet normally so it would be easy for them to say yes..
But you can use dried yeast just as successfuly.作者: 移木花道 时间: 2011-11-10 13:39:18
