Hello, all,

I tried to make a yeast-bread tonight, but it didn't rise at all. I
bought the yeast 1 week ago. I spread it in warm milk, but it came into
a cluster, but not dissolved at all. I made yeast-bread few years ago.
When I put yeast in warm water, it bubbled, but not this time. The
yeast I used is Active Dry Yeast. It's winter time now so I guess the
rising time is needed longer. Therefore, I put the dough for over 3
hours. When I pour yeast mixture in mixing bowl, it's not warm or hot
at all. Does it matter? Is there any possible reason why the dough
doesn't rise at all?

Thanks to all!
