Yeast is not foaming and I just bought the bottle of yeast and opened it

I am in the process of making babka and need to use yeast. I followed directions, 1/2 cup warm milk, pinch of sugar, 2 1/4 tsp of yeast. I warmed the milk, add a pinch of sugar, added the yeast. It is taking so long for the yeast to get foamy.. I dont know what I did wrong? Directions and video did not say to stir it.. Please advise. Thank you!

Probably either the yeast was dead when you bought it or your milk was too warm. Unless your room is freezing cold, unlikely in July, it shouldn't take more than 10 minutes to be noticeable. I'd try again and be careful with the milk- if you've tested baby bottles, that's about the temperature you want.

ps you should stir it- dried yeast is actually coated with dead yeast, and is a little slow to dissolve, but not stirring shouldn't be as much of a problem as what you describe.

Thank you so much.!I did exactly as you mentioned, and this yeast must be dead. Going out to get more:)
