Yeast Question

[adejesus]

A friend gave me two packs of yeast but he never kept them refrigerated are they worth trying out or am I better off getting a pack and using that instead?

 

[gratus fermentatio]

If it's dry yeast, still sealed & not past the expiration date, it might still be good, provided it wasn't exposed to extreme heat or cold. Only 1 way to find out though; rehydrate & make a starter.
