Storage of bulk dry yeast

[andiesenji]

Ditto to Julie, Maddy & Cookie1.

I actually checked the used by date on mine after reading this and it was out by a few months.  I used it on the weekend without issue for the crumpet recipe from this forum.  So will keep using until I have a floop and replace with new.

Cheers,
Katie

You can, from time to time, do a "test proof"  - 1/4 cup warm water, 1/2 teaspoon sugar - 1 teaspoon yeast - stir and leave it for 30 minutes or so.  If you get a foamy result = yeast still active.  If it just lays on the bottom of the cup = yeast dead.   Simple.

Thanks Andie, can you then use that mixture.  1 tspn yeast doesn't seem enough for anything I make though.

[andiesenji]

No, it should be discarded.

Hey Andie,
Thanks for this.  Will give a a whirl every few uses to ensure yeast is still active, but it does seem that storing it in the freezer extends the shelf life of the product.

Cheers,
Katie
