I have some yeast that has been in the freezer for several years. I'm
starting to make bread again and would like to know if it's still good.

I tried 1/4c warm water, 1/4 tsp sugar, and sprinkled a small amount of
yeast over the water to cover it. Put it in a warm place. I see a little
bubbling and a meager layer of gray foam on the water after about 10-15
min. Is the yeast good? I suspect it's barely active. I've not done this
for years but seem to recall lots more bubbles and foam. Maybe I didn't
use enough yeast? Or sugar?

TIA

Ken
