Top! I keep a supply at home and whenever I decide to bake something yeasty I just pull it out. Much better than having regular yeast in one and worrying about it going bad.
I think I did something wrong because it didn't activate for me. I am however not very good at baking in general :D
Unfortunately, this is the third time I have failed to bake with this yeast... And I bake often and for a long time. But the dough didn't rise at all. Maybe a bad batch :(
