What if the cake noodles don't rise?
In northern China, locals like to call cakes made of wheat flour and flour "hair cakes", which are made of many materials and can be mixed with miscellaneous grains. Hair cakes are different from steamed buns and steamed buns. Hair cakes are often soft and more suitable for children and the elderly.
The common reason why cake powder does not rise is that there is less yeast powder. If you use miscellaneous grains as cake powder, the moisture in it will aggravate the dough, and naturally you need more yeast powder. In this case, you can melt the yeast powder with warm water, add some sugar appropriately, and then put it into the dough for fermentation.
In general, the fermentation time is at least 1 hour, and the cake fermentation time cannot be shorter than this time. If you see that there is no fermentation, it is likely that the fermentation time is not enough. Continue to cover with plastic wrap, and then ferment again.
